I've written a remote-memory system for a thesis of mine. As a result, I'm able to setup a diskless client that swaps to remote memory instead of a remote disk. The specifics, reasons, and design of the system are a long story.... However - this system allows for much faster page-fault latencies (on the order of 10-20 times faster than using a disk for swap space). The problem is: I cannot get the swapper to page-out or page-in data any faster. My end question is: how would one DRASTICALLY increase the rate at which the system does its paging in freebsd? Everthing I find on the net says "don't mess with freebsd's VM system or you'll die and go to hell." However, I do in fact need to drastically increase the paging bandwidth. Anybody know how? Preferably during runtime? Thanks a lot. /*********************************/ Michael R. Hines Grad Student, Florida State Dept.
