seems yes, max and turbo working

very very good man.  :)

check sometimes ethtool -S eth2  and eth5 for errors, if some "bad" counters increasing

in my case with Intel(R) Xeon(R) CPU           E5506  @ 2.13GHz and 1k users load average is 0.01, have 1.2 Gbps traffic at now

sometimes tuning ring buffer (increasing slightly) and adding coalescing over ethtool -c might help to gain few % of performance, but better to not touch, if everything ok

Cpu work in low speed mode at 1600 Mhz

load highly depends on amount of firewall rules

show

:D

Alex, and dynamic cpu frequency might cause crashes sometimes, i am avoiding clocking to low frequency
on some hardware it is ok, on some not

if any of this increase - its bad

Denys, agree for not stable work in different systems

(root@accel02)[~]# ethtool -S eth2|grep flow

i som worry about this

this one is internal hashing, no worries

Is this rx_errors problem with fiber module or cable?
