I went to the release notes of firebird 1.55 (the latest) and
"experimental" is yet there. In anyway, it's a very good news for me
because it open a new perspective on deploying firebird with likely an
increase of performance on multi-core servers.

About page cache (DefaultDbCachePages) with page size=4k, I well
understood for evident reasons that high value is impossible on classic.
However, on SuperServer, You precise that this conf entry must be let
between 128 and 512. Even when the server has 4Go ram (1 mega pages),
does this rule must be observed , especially if there is no other
application, as I mentionned? It would be obvious that the caching
pages is done in ram since memory is yet highly availabe. I don't see
any reason making the os playing that on disk while lot of ram is free.
So let me please ask again my question : why DefaultDbCachePages=20480
on FbSS (with well dimensionned server entirely devoted to firebird)
could by a "typo" ? In other words, if there is no risk to occur on
disk but on ram, is it a good practice to put so high value ?
thanks.
