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

With which timecounter?
I guess the default as it is not set anywhere (in linux it can be changed only during boot time i think)
Do you have idea how can I see the current timecounter on linux ? :)

This is what I found in dmesg:

time.c: Using 3.579545 MHz PM timer.
Calibrating delay using timer specific routine.. 4416.34 BogoMIPS (lpj=2208170) Calibrating delay using timer specific routine.. 4409.37 BogoMIPS (lpj=2204688)
Using local APIC timer interrupts.
Detected 12.528 MHz APIC timer.
Disabling vsyscall due to use of PM timer

I guess this means that ACPI timer or PM Timer is used? :)

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
