Hey! Happy new year to all!

For me, it should have started with something great, new...
FINALLY! The migration from FB 1.5 to 2.5 (trust me, I had reasons not
to do it earlier). But now the old appications are all gone, and I can
migrate.

Seems there will be a delay. I migrated the database from old hardware
running 1.5.4 to new hardware running 2.5.3. Backup/Restore is about 4
times faster. Wow!
But normal working is - at least - 50% slower sometimes worse.

I already scanned the newsgroups and noticed that other users had the
same problem, but none of them seems to have found a good solution.
For me - being only a part time wannabe administrator - I really don't
have a clue where to start looking.

Here are some details of the 2 systems; if anybody can point me into a
direction where to look first it would be most welcome.

[Old]
Server 2003 x86 no service packs
Xeon with 4 GB RAM
Classic 1.5.4 (x86, of course)
Raid 0 on 2 * 500 GB SAS (though this is from memory, I should look it
up...)

[new]
Server 2008 R2 x64 SP1
Xeon with 8 GB RAM (I will shortly add +8)
Classic 2.5.3 x64
Raid 0 on 3 * 600 GB SAS

In comparison to what I read from others, my databases are small.
Biggest database is some 1 GB only.
Bad performance on updates and inserts and extremely bad performance
on committing a big number of record changes (~ 150.000 updates).

Database has 4096 Page Size and 2048 buffers (which sounds like
setting for SS but I specifically set it higher to use more RAM
according to a hint from experts).

While testing the configuration, nobody is in the network.
Firebird runs on dedicated server (just windows and Firebird).

where to look?
