Hi,
      
      
      
It is fixed in 2.1.5, 2.5.2 and 3.0.
2.0 does not have this fix, end of life was announced.
      
The problem is described here
http://dyemanov.blogspot.ru/2012/03/firebird-vs-windows-file-system-caching.html
      
      
In essence, Windows will try to cache whole database in memory, due to file access flag.

Hi to All !
In http://www.slideshare.net/ibsurgeon/resolving-firebird-performance-problemspage 7:
"All architectures of 32 bit Firebird will work bad at 64 bit Windows with mem>4GB, fixed in 2.52 only"
This means database will crash, or only not more/enough speed ?
Experiences ?
My partner would like to change the server's mem 4 Gb to 8 GB in the next week, but .. ?
The 64 bit Firebird not option now, it's only my plans, 4-6 months later.
Thanks in advance.
