Follow-ups

--- Graf Yang 2008-10-21 04:52:54

I can't duplicate this issue. Maybe out of date?

--- Vivi Li 2008-10-22 03:57:56

This case still fails in the test machine.

--- Graf Yang 2008-11-14 04:25:51

I have add a parameter to malloc-perf to give the desired performance value.

For UP kernel, you can directly run malloc-perf, or 'malloc-perf 100'

For SMP case, you can relax the desired performance, for example, 'malloc-perf

120'

--- Graf Yang 2008-11-18 05:08:57

Because SMP are software cache coherency, it's threshold may exceed 100, I

recommend to use 120. Now can close it.

--- Vivi Li 2008-11-18 05:15:08

OK, I have modified the test script and it works all right now.

So close this bug.
