And that's where I missed the mention of Ubuntu. Sorry.
You can check what it's running at by do:
cat /boot/config-<kernel> | grep HZ
Where <kernel is the version you are running>
Examples:
Ubuntu Jaunty
$cat /boot/config-2.6.28-11-generic | grep CONFIG_HZ
# CONFIG_HZ_1000 is not set
# CONFIG_HZ_300 is not set
CONFIG_MACHZ_WDT=m
CONFIG_NO_HZ=y
CONFIG_HZ=250
# CONFIG_HZ_100 is not set
CONFIG_HZ_250=y
Oracle EL 5
$ cat /boot/config-2.6.18-164.el5 | grep CONFIG_HZ
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000
For Ubuntu, you'll want to investigate "make menuconfig" to compile the
kernel with a different timer if not set @ 1000. The relevant option is
"Timer frequency" under "Processor type and features".
There are also other settings on modern kernels that you can look into
that may yield what you want, such as CONFIG_HIGH_RES_TIMERS, without
having the change the frequency of the clock. There's even an option to
go tick-less with CONFIG_NO_HZ. I don't have experience using either of
these, but they sound interesting based on a little research.
