Re: [CentOS] Performance of CentOS as a NAT gateway

Bart Schaefer napsal(a):

I can't find any recent statistics for Linux NAT performance, but the older stuff I can find (e.g. 50k packets/sec for a P3-450Mhz) seems to indicate that the gateway should easily be up to the task of handling the NAT traffic. Am I wrong about this? Is there any way to diagnose whether the NAT is the bottleneck? Would we benefit from upgrading to a newer CentOS (2.6 kernel as opposed to 2.4)? Or is it more likely to be the switch, in which case what would be a recommended replacement for the Linksys?

Bart, how many connections are on the router (/proc/net/ip_conntrack) ? And what's the /proc/sys/net/ipv4/ip_conntrack_max David
