Do you mean does it decrease performance? – ErnieTheGeek Jul 14 '11 at 14:33
I am talking in the context of a server that hosts a bunch of web services. So like an increase in response time. – Reflux Jul 14 '11 at 14:59

If you have 32-bit apps that could use more than 2GB of virtual memory (4GT increases it to 3GB) then yes, you might benefit from enabling it. If your apps are network or IO heavy however, the memory available to those operation will be reduced and you may experience degraded performance. It really depends on the situation and the apps you're running. Experimenting may be the best way to find out.

Microsoft's article on 3GT explains in more detail.
