PA RISC CPU clock frequency

Hello,

this should be easy to answer.

I guess the model command should reveal it (though cstm doesn't), but I need a confirming reply that my assumptions are correct.

I've got two boxes for which the model command issues:

# model
9000/804/K450

and

# model
9000/800/N4000-36

Now I would interpret that the K450 is supplied with CPUs clocked at abt. 450 MHz whereas the N4000 merely gets 360 MHz.
However I believe other measures (such as cache size) are more important.

I need this info to satisfy some application consultant for their performance measurement report.

Not sure about model.

clock frequency --
echo "itick_per_usec/D"|adb -k /stand/vmunix /dev/kemem

or

echo "selclass qualifier cpu;info;wait;infolog"|cstm|pg

You should have stm installed.

covers most issues ..

The K number is nothing to do with the CPU clock frequency. A K450 actually uses a PA8000 chip clocked at only 160MHz.

The N4000-36 however does indicate a 360MHz clock speed.
