Subject Re: Classic vs SS
Author mivi71dk
I thought that SS just started one instanse of FBServer and that windows and linux wasn't able to use more than 1 CPU.
I was under the impression, that both windows and linux would swap the one instance between the two CPUs.

Whereas Classic would start on FBServer per connection and that this was more efficient on both linus and windows.
