[mpls-linux-general] Problem with CPU overload in older PCs

[lucapilosu\@libero\.it <luc...@li...>]

Hello,
I'm doing some measures with traffic generators within a MPLS network.
My first LER is a Pentium 3 @647 MHz, and if I run the command "top" on it, I see that the CPU load grows rapidly ove 96% as soon as I start sending traffic (at the moment I'm sending 8Mbps, due to ksoftirqd (what is it?) resulting in dropping packets from my flow without a predictable principle.
Do you know if it could be MPLS that boosts the CPU load this way?
Thanks,
Luca

Did you disable debugging in mpls? Something like echo '0' >
/sys/mpls/debug. Once you do that performance increases very much!
