On the ElanSC520 CPU use general purpose timer#2 as timecounter.

This is a vast improvement over the i8254, since it is a simple
memory load rather than a comples sequence of interrupt blocking,
multiple input/output instructions, and wrap-around detection.

I have not bothered to time the fundamental timecounter get routine,
but gettimeofday(2) is 10% faster with the ELAN timecounte.

The downside is that HZ=100 is not enough, 150 or more recommended,
I use 250 myself.
