gettimeofday() in hping

Greetings,

I noticed that hping3 (from ports) is quite slower when running on 
FreeBSD compared to Linux.
Simple ktrace shows lot of gettimeofday() calls, so I'm looking for 
replacement of this function.
I tried clock_gettime() (using CLOCK_REALTIME for clock_id), but this 
yield worse performance.
Of course changing timecounter to TSC make hping almost twice faster, 
but I'm wandering if I can optimize things more?
