Profiling

Some tools to profile linux:

• OProfile, a kernel profiler with low overhead and that uses cpu counters.
• xenoprof, oprofile port to Xen linux domains (domU/dom0).
• Systemtap, a kernel tracer (like dtrace for solaris and *bsd).
• Frysk, always-on system monitoring/debugging tool.
• qprof a kernel profiler (not tested)
• sysprof (not tested)
• Prospect (not tested)
