Subject: [Question] SMP for Linux
Date: Thu, 17 Oct 2002 11:29:28 +0900 [thread overview]
Message-ID: <20021017112928.B20854@toad.postech.ac.kr> (raw)
Many people helped me to solve the interrupt distribution problem.
We tested the throughput of Layer 3 forwarding on a SMP machine
which equips two Zero proessor(2Ghz). This is our results:
-------------------------
SMP | No SMP
-------------------------
230 Mbps | 330 Mbps
-------------------------
We use RedHat Linux 8.0 (which uses Linux Kernel 2.4.18-14) and
two intel Pro1000 Server Adopters. In the table, SMP means we
use the kernel builted for SMP Machine, and "No SMP" means
the kernel builted for single CPU mode.
I expected that the SMP might show better throughput than "NO SMP"
environments. But, contrary to my expectation, SMP showed poor results.
I don't know what is my fault in the experiments.
