OK...it just occurred to me that what we're talking about here is a CACHE program...one that basically stores enough data to be able to re-read the same data at a later time / date without wasting a lot of time.

It stands to reason that if a cache were allowed to become extremely large then the entire purpose of the cache would be defeated for it would take far too long to locate then extract the much needed information / data. This would in turn cause the program to slow down on the user's end.

I think when they said to let the program manage it's own memory cache, it is most likely the best thing to do.

We're trying to wring a bit more effectiveness from a system that's already doing a pretty fair job.

Lol, Art. And if the secret of a smart SL were having just a brand new PC, with a powerful CPU, a lot of RAM, a fast hard drive and a good graphics card? Wondering... ;D

Well GT, my friend, unfortunately, it is often true with a lot of things in life...

Size does matter!! :o

EPILOGUE - Not a good idea. Finally...

I started my little experiments with the SL cache because... I like to do little experiments. Also because I always thought that the cache was not effective enough:

http://jira.secondlife.com/browse/VWR-9509

And finally, after testing different configurations (cache in RAM or on HD, 250 to 500 MB), I went back to a classic cache. Just a few figures:

When I start SL and arrive on the welcome/logging page, SL uses 85 MB in RAM. Then, after rezzing, the used RAM increases and increases during a SL session. With my low Preference Settings, I always need less than 650 MB. It means (IMHO) that SL stores all the needed things (loaded from the cache or from the internet) in this part of the RAM.

I also noticed that a cache in RAM loads less datas than a cache on HD, in the same conditions. A cache in RAM seems useless.

And after testing a lot, I finally found no real difference between the loading speeds, with always the same anomalies explained above. A cache in RAM avoids the hard drive to work, but a cache on hard drive is more comfortable.

But it was worth to try. ;D
