32 meg per sort can be a lot in total if you have many clients sorting 
things. I assume you have checked so that the computer is not pushed into 
swapping when you have the peak with lots of users. A swapping computer is 
never fast.

Using some swap space is not bad, but a lot of page in and page out to the
swap is not good.
