Yeah: upgrade to vfp9, where you can:

if version(2)=0
  set coverage to "C:\SlowDown.Tmp"
  goTmrPurge = createobject("LogPurge")
endif

define class LogPurge as Timer
   intervall = 60000
   enabled = .t.
   function timer
      set coverage to
      DoEvents
      delete "C:\SlowDown.Tmp"
      set coverage to "C:\SlowDown.Tmp"
enddefine

But seriously, I have a special testing pc where I can test any apps performance with combinations of:
different the cpu frequencies
different ram size
different bus speeds
different harddisk speeds (including laptop disks)
different network speeds
different OS

In case of xCopy deployment I usually can get a matrix of perf differences pinpointing the worst current bottleneck quite fast. It also helps finding the best hardware upgrade for deployment pc's.
