Subject Re: [firebird-support] cache
Author Ivan Prenosil
I think 10000 is not any magic/fixed number. I believe there is simple (linear?)
correlation between cache size and CPU required to maintain it,
so just do a practical test to find out which value is best for your configuration.
Also do not forget that Firebird uses lots of other memory (besides cache)
for other purposes, like for compiled triggers/sp, transaction lists,
sparse bitmaps, sort buffers, ...
