How much can Linux handle?
Will install ubuntu on the same machine and let you know, but my
experience shows that FreeBSD + TSC
have the same performance as Linux.

If you do, it would give a nice indicator of how much the time
counters are expensive in both absolute terms and relative to the rest
of the stuff the program does (network IO). The "dummy" timecounter
just increments a number when called, no time keeping is involved.
Here are the max speeds I can reach with different counters (on the test
server):
i8254 - 3.660 MB/s
ACPI-fast - 7.137 MB/s
TSC - 12.519 MB/s
dummy - 12.366 MB/s
