If there is, not without some truly horrendous hacks. If OSX is slowing down, you don't have enough RAM to run what you're trying to run. Disabling vm is not the answer.
From Apples Performance.pdf (well worth downloading from http://developer.apple.com/techpubs/macosx/SystemOverview/Performance/Performance.pdf:
On Mac OS 9, all processes share a global, fixed-size 32-bit address space. Whenvirtual memory is enabled, a backing store file is created on a user-specifiedvolume. The size of this file, and thus the amount of available virtual memory, is
fixed at a user-specified setting. The file serves as a fixed-size container for allphysical RAM plus all additional virtual RAM. On a system with 64 MB of physicalRAM, a 65 MB virtual memory setting offers only one megabyte of virtual RAM.Additionally, because of limitations of the Mac OS 9 multitasking architecture,real-time processes (such as audio/video playback) may be starved for executiontime during even short periods of paging activity. Because of these and othersoftware compatibility issues, users of Mac OS 9 are allowed to disable virtualmemory. This is not necessary in Mac OS X.
