Display profiling statistics.  The output will show the mean, standard deviation, and instance counter for each enabled profiler.  For example:

    iPXE> profstat
    intel.vm_poll: 22775 +/- 59514 ticks (16275 samples)
    intel.vm_refill: 28313 +/- 14967 ticks (5800 samples)

    net.tx: 73221 +/- 55247 ticks (23181 samples)
    net.rx: 88603 +/- 57188 ticks (23180 samples)
    net.poll: 34474 +/- 64185 ticks (16274 samples)
    ipv4.rx: 88161 +/- 57176 ticks (23179 samples)

Profiling is enabled for any objects built with [[:download#debug_builds|debugging]] enabled.

===== Build options =====

This command is available only when the build option ''[[:buildcfg:PROFSTAT_CMD]]'' is enabled.

===== Notes =====

You can enable profiling for an object without simultaneously enabling debug messages by using a debug level of zero.  For example:

    make DEBUG=netdevice:0,ipv4:0
