Minimum Memory Cache and Size-adaptivity
By Colonel ONeill | January 1st, 2009 | 8:57 pm
I amd unable to set the system memory cache lower than 64mb using the textbox, and no less than 256mb using the slider. Ignoring the discontinuity… is the low end of 64mb fixed regardless of the total memory in the system?
With 320mb of RAM, devoting 64mb to a cache, that for the moment does not seem to be size adaptive like the Vista counterpart, it actually begins to impact performance when using more memory intensive applications (and their combinations).
Photoshop on this system becomes a bit more sluggish, and so does Microsoft Word (don’t ask me why). This behavior becomes pronounced especially in the presence of Firefox 3 (for well documented reasons).

I think there is no reason for shortening system resources and use memory cache at system with < 1gb memory. The main purpose of memory cache is use memory which is not used by os and apps. In you case fast USB flash drive will give optimal performance.

True, but I have seen a few notable speed increases in program startup. (Kaspersky IS 7 updating doesn’t drag my system down as much as it used to).
But the thing is, I would use a flash drive, if my USB bus wasn’t 1.1.
A USB 1.1 bus can only push 12Mbit/s of data through, whilst most computers nowadays have a USB 2.0 bus, capable of 480Mbit/s transfer speed. So you can see how using a USB flash drive is unfeasible.
As for the RAM, when I have eBoostr eating 64MB of RAM… Photoshop becomes a pain to use in conjunction with Firefox (often necessary for editing of images from the web).
It would be VERY nice to have an adjustable cache size without having to Remove/Readd the cache. It would also be nice to have the minimum RAM cache size to be set to 5% of total system RAM.
