One nice tweak is to activate Superfetch only for boot and Prefetch for both boot and applications. So, if you're using eBoostr you may deactivate ReadyBoost, related ReadyBoot and Superfetch for applications. My computer is now running silently without that inicial HDD noise and almost in a way that only XP did. I'm convinced that, if ReadyBoost is activated and we're using Intel TurboMemory in NVCache, eBoostr accelerates this cache that's why speed measures are so high (in my system about 10 times more then without TurboMemory). Maybe if there was an option to exclude NVCache we could try another configuration in order to optimize everything but ReadyBoost cache. Configs: Total memory installed: 4GB; RAM: 3GB; eBoostr Unmanaged Memory: 1GB, NVCache: 500MB. Greetings.

If you tell eboostr to load lots into memory it will do so, but it will slow down the boot by 1 second for every XXXmb/s your disk goes, pf might be faster because it loads less, but in my case it was 10 seconds slower. You are loading 1.5 gig off the disk during boot so you need allow for that. If you have a harddisk then use USB as well, just make sure your USB stick is fast and the USB2 hub is not gimped. If you have a really good SSD then it is pretty pointless to run USB caches. Even the memory cache is overkill, but we like overkill ;oP zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1062 Fri, 29 Jan 2010 06:26:17 +0000 zPedro 1062@http://beta.eboostr.com/forum/ It seems Prefetch doesn't work if Superfetch is deactivated. One nice possibility is to deactivate Superfetch when playing games. I stil don't think Windows and programs are faster opening only with eBoostr (without Superfetch). Perhaps Chooky should try his tests with HDD and not only SSD. zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1060 Thu, 28 Jan 2010 18:01:41 +0000 zPedro 1060@http://beta.eboostr.com/forum/ I had to repair prefetch restoring layout.ini. zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1059 Thu, 28 Jan 2010 11:00:24 +0000 zPedro 1059@http://beta.eboostr.com/forum/ zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1058 Thu, 28 Jan 2010 10:59:41 +0000 zPedro 1058@http://beta.eboostr.com/forum/ <blockquote><cite>zPedro <a href="http://beta.eboostr.com/forum/topic/superfetch#post-1058">wrote</a>:</cite> Another thing: Against every advise, I've tried to clean and deactivate Windows prefetch folder, just to see my laptop behavior without ReadyBoost, Superfetch and Prefetch. Only eBoostr working. It seems that deactivating Prefetch is not the best idea of all. However, after reactivating it, I can see no files in there, except a folder named ReadyBoot with a 20 MB file named ReadyBoot.etl. It seems that Windows is not using Prefetch but ReadyBoost does even if it has been deactivated. A quick search on the internet gave me the following information that I prefer to paste here. It's in <a href="http://talkback.zdnet.com/5208-12354-0.html?forumID=1&threadID=47786&messageID=895626&start=0" rel="nofollow">http://talkback.zdnet.com/5208-12354-0.html?forumID=1&threadID=47786&messageID=895626&start=0</a>. "For anyone who's going to disable ReadyBoost it's also a good idea to disable the related but different ReadyBoot. (...) Here's how to disable ReadyBoot. Launch the "Reliability and Performance Monitor" program (under "System Tools" inside "Computer Management"; or via any of the other routes to launch this program). Then on the lefthand side of your screen click "Data Collector Sets", and underneath that heading click "Startup Event Trace Sessions". Now on your righthand side you'll see a list that includes ReadyBoot, and you'll see the word 'enabled' beside the word 'Readyboot'. Double clicking the list item brings up the ReadyBoot Properties dialog. This dialog has a number of tabs. Pick the "Trace Session" tab. Finally, uncheck the "Enabled" checkbox on that tab." As I'm not using ReadyBoost I followed this recomendation and, as matter of fact, I notice that inicial activity slowed down a lot. </blockquote> zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1057 Thu, 28 Jan 2010 10:00:44 +0000 zPedro 1057@http://beta.eboostr.com/forum/ I agree with you, mradr. I tried eBoostr unmanaged memory (1GB) on (+ 500 MB NVCache) and Superfetch off playing Fifa 10 with my nephew and it ran quite well in my laptop. As you advised before, I don't exclude anything from eBoostr cache. I let it choose. mradr on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1054 Thu, 28 Jan 2010 02:41:19 +0000 mradr 1054@http://beta.eboostr.com/forum/ Thats why you should turn it off when running eboostr. SuperFe only helps with start up while eboostr helps with start up and running the software. The only big differents is that SuperFe will give up its ram for a program and eboostr wont just yet, but if you have more than 4gb and a 32 bit system, then you are set with one gig for eboostr and 3 gigs for the game. This would work for even 64 bit. -Most- programs don't really use more than 3 gigs anyways. Thats why I'm going to say its ok to disable superfetch when running eboostr or keep it on when not using eboostr. zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1051 Wed, 27 Jan 2010 12:20:23 +0000 zPedro 1051@http://beta.eboostr.com/forum/ Thank you jujdred! Don't you think that for gamers, who need every ram that it's possible to get, unabling superfetch and using unmanaged memory with eBoostr could be a nice way to upgrade their systems (at least in laptops)? jujdred on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1046 Wed, 27 Jan 2010 03:25:42 +0000 jujdred 1046@http://beta.eboostr.com/forum/ This is for Vista. Superfetch is different from XP's PREFETCH. Prefetch was a mistake, but it was necessary to get where we are now. It really is an amazingly "smart" piece of tech. I would highly suggest you leave it ON. If you really feel the "itch" to turn it off, at least know what it does first. However, there is a catch. Many Vista users (or people who have never used Vista) complain that the operating system uses too much RAM. They look at the performance monitor and see there is a lot less available RAM – when compared to Windows XP. The extra use of RAM in Vista is partly due to a performance enhancement called SuperFetch. Having low free memory in Vista shows this is working. Please note: I wrote a guide on disabling Superfetch. In this guide I tell you to let Superfetch run. My advice is to disable Superfetch if you have less than 2GB of RAM (this is a generalized number as all systems are different.) If you have more than 2GB of RAM, Superfetch will work to your advantage. XP treats RAM as a resource to be used only when needed while Vista treats RAM as a cache and uses almost all of it as soon as it becomes available. Also keep in mind, Superfetch ONLY increases the performance of OPENING a program, not running the program. Big difference. That is another world of it's own comprised of pagefiles and RAMDisks etc. Windows 7 is basically Vista, but "fixed" and "enhanced". zPedro on "Superfetch" http://beta.eboostr.com/forum/topic/superfetch#post-1032 Sat, 23 Jan 2010 08:21:47 +0000 zPedro 1032@http://beta.eboostr.com/forum/ Thank you, mradr!

Some defragmenters are better than others. Unfortunately I have never found a good free one. After trying every one available I recommend Disktix products <a href="http://www.disktrix.com/" rel="nofollow">http://www.disktrix.com/</a> I own the Ultimate Defrag but also recommend Defrag Express for the budget conscious. Give them a 2 week trial for free and you will see a difference. The first defrag will take a long time. The defragger should then be scheduled to run whenever the PC is idle. PangOS, interesting results! I think the only way to test it properly is with Apptimer <a href="http://www.passmark.com/products/apptimer.htm" rel="nofollow">http://www.passmark.com/products/apptimer.htm</a> Make sure to reboot between tests of the same application, it is the first load time after reboot that eBoostr affects the most. Just use a couple of applications such as MS Word or MS Excel. You also have to make sure the application you are testing are cached nearly 100% by checking in the eBoostr Cache Statistics program. I am fairly sure eBoostr does not cache documents. I have read that they made a few improvements to readyboost and superfetch in Windows 7 but I don't think they work anywhere near as well as eBoostr!

Please note, that if you disable and then enable it (or resize)--it needs some time to be actually loaded, so please wait for the hard disk activity to stop and only then run the speed check.

Let me retest. #1 *************************************************************** Cached access with the usb eBoostr (4GB) ReadyBoost (10GB) 92.62 MB/sec Ratio 3.43. --------------------------------------------------------------- #2 *************************************************************** -- Assigned 2048MB RAM Cache in eBoostr -- Disabled USB for eBoostr -- Disabled ReadyBoost -- Direct: 15.11 MB/sec Cached: 31.93 MB/sec Ratio: 2.11 --------------------------------------------------------------- #3 *************************************************************** -- Assigned 2048MB RAM Cache in eBoostr -- USB enabled eBoostr (4GB) -- Disabled ReadyBoost -- Direct: 14.86 MB/sec Cached: 26.26 MB/sec Ratio: 1.77 --------------------------------------------------------------- #4 *************************************************************** -- Assigned 2048MB RAM Cache in eBoostr -- Disabled USB for eBoostr -- USB & SD ReadyBoost (10GB)-- Direct: 30.05 MB/sec Cached: 353.45 MB/sec Ratio: 11.75 --------------------------------------------------------------- So according to this, ReadyBoost increased Direct access x2 and Cached access exponentially. (Should I trust this?) Another question is raised in my mind... (Still awaiting the answer on fragmentation): This cached acceleration only serves to *launch* Applications faster? It should also mean applications can open documents faster? Writes to disk remain the same? This may not serve any real purpose for users that launch a set of apps and leave them running, never really launching other apps or relaunching the ones that they already have open. This reminds me of my first experience with Vista ReadyBoost - while playing a game it was very jerky and sometimes unresponsive -. I turned my back on ReadyBoost, however Win7 ReadyBoost did not exhibit this same behaviour, It worked well. So I will continue using it combined with eBoostr.

It's a well know fact that heat shortens the life of hard drives (sometimes considerably). If file fragments aren't scattered all over the hard drive, the hard drive doesn't have to work as hard, which means it should run a little cooler. This is especially important for hard drives that tend to run a little on the hot side (or near the maximum operating temperature recommended by it's manufacturer). chooky on "eboostr and Superfetch" http://beta.eboostr.com/forum/topic/eboostr-and-superfetch/page/2#post-308 Thu, 01 Oct 2009 08:12:45 +0000 chooky 308@http://beta.eboostr.com/forum/ Thanks for all the info PangOS! Looking forward to see how you go with the 4GB cache! That is a very good ratio considering you have a USB cache in the mix. The more PC's I try eBoostr on the less faith I have in the Ratio being a good indicator of anything. Today I was at a friends place working on his PC's, he has an old Dell notebook running XP and a new Dell Vostro 200 running Vista. He wanted to upgrade them so we replaced the notebook HDD with a Seagate MOMENTUS 7200.4 500GB SATA 2.5 7200rpm 16MB and the 1GB of memory with Corsair 2GB Kit(2x1G) PC5300 667MHz DDR2 SODIMM. I also installed eBoostr 4 and set up a 800mb RAM cache. The speed test gave a ratio of 19! On the desktop PC we replaced the 1GB of 667Mhz RAM with Kingston DDR2 4(2x2G)PC6400 800Mhz - KVR800D2N5K2/4G. I installed eBoostr 4 and setup a 2GB RAM cache and a 1.5GB USB cache this ratio was 2.1. I tested both C: drives with Crystal diskmark and the notebook HDD was actually faster. The performance difference in both machines was astounding the old notebook was performing much the same as the new desktop! What was even more amazing was that both cheap, low specification, not O/C'ed machines were opening Office apps nearly as fast as my expensive, high specification, O/C'ed beast with SSD's in RAID zero.

Personally I have never noticed any differences in speed after defragmentation and honestly believe that the benefit only applies to persons doing recordings and so on.

I think you would have to do some methodical testing to see what is going to give you the best performance on your system. As a general rule I have found the more you cache on slower media USB,SD,HDD the slower your performance. Your system will have an optimum RAM cache size depending on the amount of memory you have and the size and number of programs you run. Making a larger ram cache will just cause you to start using the pagefile more when your programs are using more memory.
