Slow cache building

Builds cache too slowly. Improving cache building algorythm could be very useful.

USB device cache storage capacity selection

By lonesh | |

Well, I managed  to get it working somehow, but now I canot select the maxim storage capacity offered by my usb memory stick using the selection screen. It’s got 1 GB , and I can only select 960  mb.Strange issue indeed.

Bootup: Slower with RAM cache?

By Moonie | |

I’m running Windows Vista Ultimate 64bit on a laptop with 4GB of RAM, originally I was just using a class6 SD-Card solely dedicated as the eBoostr cache, and I did notice a significant performance gain both in normal operation and in system startup.

When I read Build 482 optimized RAM for startup, I allocated 512MB out of 4GB of system memory for cache in addition to my 4GB SD-card cache, and the system seemed to boot up slower than when I was just using my SD-card.

I’m just guessing here, but since RAM contents are cleared when the system is completely shutdown, then populating the memory cache is loaded from the eboostr.dat file on the hard disk, and it seems slower because it is just like starting a computer without eBoostr, where all files are loaded from the hard disk into system memory, in this case into the memory cache allocation from the eboostr.dat file. So if this is the case, then memory cache is only beneficial once the cache has been populated from disk already, which is after the computer has booted up. It seems that reading small random startup files are much faster from flash memory than directly from hard disk especially if the disk is fragmented, hence the bootup of a system is faster when startup files are read from flash memory media. So I dont understand how memory cache speeds up bootup time.

I removed the memory cache allocation and am just using the SD-card as my cache device again, and the bootup is back to what it was before allocation the memory cache.

Again, Im just guessing here, someone please correct me if I am wrong.

Critical crash report

Crashes/freezes again.Don’t know what to do !

Crash

By lonesh | |

It crashed my xp ! I don’t know why , but when I started Eboostr 3 beta, my Windows freezed. I had to restart.

Files in cache that don’t exist…

By fastest963 | |

I checked the cache viewer and I noticed that some files are cached, but no longer actually exist.  How often does eboostr check its cache against the actual filesystem?

The files I noticed were mostly old files from My Documents and Desktop.

Allocating cache file on NTFS and FAT32

By fehmi | |

It took several minutes to allocate the cache file (4 gigs) on my flash drive, OCZ ATV 4 GB, when it was formatted using FAT32 file system but the building cache process was fairly faster. When the change log for build 482 stated faster speed for building cache, I removed the previous cache file and rebuilt it. I didn’t notice any speed increase but then I decided to format it in NTFS.

Allocating the cache file is blazingly fast on the NTFS formatted flash drive, I only see the cache allocation window for a few seconds. I removed the cache file once again and then rebooted but the allocating cache process is still fast! Is this a limitation of FAT32 file system? I doubt it is a placebo effect.

Option to hide the flash drive eBoostr is using

By fehmi | |

Is it possible to implement a feature to hide the drive eBoostr is using from My Computer? I have allocated the whole flash drive space to eBoostr cache, unchecked the drive letter from the options in the Tweak UI (a part of Powertoys for Windows XP) and now I no longer see the drive in any open/save file dialog boxes.

As far as I know, there is no Powertoys for Vista available and I doubt hiding a drive is as easy as unchecking a box under Vista.

Build 482 Cache Build

By Moonie | |

I just udated to Build 482, it didnt even require cache rebuild, but I still decided to do a manual cache rebuild for my SD-Card, and I noticed a huge difference in cache build performance.

I also added a 512MB system memory cache, seeing that this build has optimized memory cache for faster boot-ups, after which I manually rebuilt the cache on my SD-Card again, but when I view the cache content of the SD-Card there are a lot of “Deleted Entries” in the cache, which I am assuming are boot-up items so they have been moved to the system memory cache.

My question is if this affect the way the SD-Card cache is used, or will clear up later on?

Thank you.

Testing V.3.0 build 482 (RC2)

By sst | |

Hi, …

V. 3.0 build 482 = On a test machine : XP sp3 3 gig. ram, “1 gig EBoostr RamCache”.

————————————————————————————–

Since the build V3.0 482.

———————————–

I have found some new files, in “c:\” = C: \ Root  drive

C:\filestat.dat = It grow each minutes, the file size,  is 576K.

C:\badlnk.dat = Only 4K.

C:\eboostr.dat = 1,073,741,824 B = 1 Gig
