merge very slow

Hi,

I've noticed that a merge done with a client built with VS2008 is twice
as slow as a client built with VC6. Has anyone here noticed that too?
I've described my efforts to solve this problem here:

If anyone has any idea what could cause this, I'd really appreciate any
help.

Stefan
