Re: [mpls-linux-general] MPLS Trhoughput

Hello Topit,

Make sure you disable debugging - I think it's still enabled by default.
With debugging on, you will get lousy performance, because it has to write a
lot of information to the logs.

If memory serves me right, you need to do something like echo 0 >
/sys/net/mpls/debug (don't remember the path exactly). With debugging off
performance is about the same as regular IP.

Cheers,
Adrian
