Subject: [firebird-support] Slow writes on Vista


I develop a desktop application using Firebird embedded and ran into some
troubles with Vista.

Basically everything works. Connection is fast, read performances (loading a
10K record dataset) is fast enough, but write performances are... abysmal
compared to 2K/XP.

Everything seems about 10x slower (database creation went from 3/4s on 2K/XP
to about 30s on Vista, ...)

I've already tried/checked :
- On a clean computer (no antivirus, virtually nothing installed)
- Embedded database uses the .fdb extension
- System restore is off
- Firebird embedded DLL 2.0.1, 2.0.4, 2.1.0, 2.1.2 snapshot

The computers I tried it on are reasonably fast, and during thoses
operations CPU and HDD are idling.

I'm running out of ideas, and all my Googling, FAQ reading, ... turn up
nothing. I found 1 thread from may 2008 with someone having what seems to be
the same problem, but no resolution whatsoever.

Do you have any hint or thoughts about what might be the problem ?

Thanks in advance.
