You used to be able to compile with -DVDBE_PROFILE=1 to enable some special assembly-language instructions that would use hi-res timers on ix586 chips to provide the cycle counts needed to execute each instruction in a VDBE program. But I haven't used that feature in years so I don't know if it still works or not.
If you are talking of the "rdtsc" instruction, then to work with current dual core CPUs the test must be "pinned" to a single CPU, or you could be reading TSC values from different CPU's. Other than that, as long as the code works on a "single-core" CPU, it should work on newer ones. Off course, there is that word: "should" ;-) Regards, ~Nuno Lucas ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
