Before use windows server 2012 (i7, 8GB ram) i used windows xp profesional (dual core, 2GB ram). There is no problem with the application or queries.
I just copy the database into windows server 2012, the number of  users is same, queries is same to. everything is identical

I use FB 2.1 64 bit and try  2.5 64 bit

You say that you migrate to Windows server 2012, what do you migrate from? Is everything except the server identical on the fast and slow server - e.g. indexes and plans for all problematic queries? The same number of users and the same content in the databases? What about database statistics? If there are specific queries running slow, you could post them here together with the generated plans and some information about the fields in the indexes being used.

Besides that.

Wich FB version ?

Newer windows versions (64bit) has changed th way to manage filesystem
cache and it became a problem...
