Maybe my questions are not so 'professional' for a tester...

It depends on what you mean with "performance testing" Some people
try to measure maximum throughput of
! If you were going to test the application
performance on zLinux, what will you do? Install Linux on LPAR directly?

Great! It seems works!

I understand. Thank you! But I encountered a trouble after add COMMAND DEFINE
CPU statement in the direct file.
Below is the part of direct file for this linux:
MACH ESA 1
CPU 06
COMMAND DEFINE CPU 06 IFL
After I log on to this guest machine, I got below

Marcy,
Thanks! How to do in user direct file if I want to permanent let this IFL
dedicated to that zLinux?
I used q cpu to know the CPU id of IFL. e.g. 03 is IFL. I defined CPU 03 in
the linux user direct file. But it seems doesn't work. What else did I miss?
Be
Yes. Do CP DEDICATE USER CPU . Or add DEDICATE to the CPU
directory statement.

Everything will use the cps unless they have issued the DEFINE CPU command. So
the answer is yes.

I have question about Linux on IFL. If there is a zVM LPAR with both CPs and 1
