I'm running RHEL/CentOS 3 (2.4.21-47.ELsmp) with Broadcom NIC and BASP bonding (bcm5700 v8.1.55) When network traffic is ~12MB/sec (== ~120K packets/sec) CPU system load is growing up to 50-60%%.
Yes, I know, that small packets (~100 bytes/packet) are not optimal for network throughput, but in the short-middle term I cannot re-write our application.
Are there any network driver / kernel parameters which can help me to increase network throughput?
Replacing bcm5700 to tg3? Upgrading to RHEL 4 or 5 with kernel 2.6?
Other ideas?
Thanks,
Vitaly
