I do this too, so I'll tell you what I mean by "get better performance".
If I have my a swap file enabled, there are times when switch to an
application that I haven't used in a while (minutes/hours) and it takes
many, many seconds before it becomes responsive.
Windows has moved that application (something like Firefox at 400 megs
or maybe much more) out to disk to free up space for disk caching or
I would MUCH prefer to have a slightly smaller disk cache than have to
wait 20 seconds to task-switch to Firefox. Under those circumstances,
it ends up being faster to kill Firefox and restart it -- which seems
like a strange situation to be in -- it should never be faster to load
an application than task-switch to it.
So I disable the swap file to avoid those situations.
