I have seen this http://kaasxxx.wordpress.com/2008/01/22/linux-hz-checker/ But the script seems not to work. Does anyway know an easy way to check "HZ" in the terminal in Linux?

There's no uniform answer to this questions, as in some cases your kernel may be compiled "tickless" and not use a regular timer interrupt at all. But if you're on a traditional kernel and a traditional distro, you can find the current kernel's .config file under /boot with something like grep 'CONFIG_HZ=' /boot/config-$(uname -r).
