[RndTbl] Accurate Monitoring of system load

[Theodore]

Not sure what kind of application you are trying to monitor, however if 
its PHP there are some excellent profilers out there. I used one once to 
figure out that 99% of my buddies code execution time was spent in dns 
lookups. I forget which one it was, I did an apt-cache search php 
profiler to find it anyways.
