G'Day,
	has anyone had any experience with vmtune in the area of tuning a 
Symmetry series to page instead of swap. We have am S27 with 8M of memory
and as soon as 2 or more people start running a certain statistics package 
which uses a fair bit of memory, the system starts swapping, the load
average hits the roof (upto 21) and response time etc. drop considerably.
 It has been suggested that I could tune the system to page instead of
swap with vmtune but that this may be tricky.

Any Ideas or experiences ???

Thanks in advance
