Sorry....

This should be OS instead of SO (SO in Portuguese = OS in English :o) )

Do you understand what I say now you know that I meant the Operating
System Disk Cache ?


About 80MB FB cache on a 256MB server:
I think it's ok, if you have more memory better...

You should look when the FB server consumes all the 80MB how much are
free to the OS, look if it's paging to disk, if so, reduce the amount of
FB memory. If the server is going to disk you will not have a big
bennefit if FB keep a "big" cache since other app (or the OS) will need
to "swap".

FB will use RAM to sort result sets, if it gets low on memory it resorts
to disk sorting will be (of course) much slower.
