FreeBSD performance on single CPU.

[Channa]

Hi,

I am using FreeBSD malloc from the current working branch.
I hope its jemalloc.

I tested it on a single CPU machine i could get the following results

# ./malloc-test  1024 10000000 4

Starting test...

Thread -1094714032 adjusted timing: 103.605124 seconds for 10000000
requests of 1024 bytes.

I checked the result in the FreeBSD mailing list link given below:

http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2005-12/msg00294.html

The jemalloc gives very good results. Is that the performance is good
only on SMP?

Or on single processor also it should perform well?

But on single CPU i could see bad results.

Could anyone help me out?

Thanks in Advance,
Channa
