Re: [Devil-Linux-discuss] Bad routing performance - only app. 100MBit/s

[Udo L. <udo...@al...>]

Hi,
I'm search a little bit more and the issue is not the devil-linux and
also not the firewall-hardware!
If I move the devil-linux-firewall to an kvm-VM the performance is the
same - but if I use only virtual clients the troughput is good (1 - 1.4
Gbit/s).

It's must be something to do with the switch... strange that the
performance from all network to the firewall reach "full" speed, but
routed not.

Must look further to find the issue.


regards

Udo
