comparison of identical servers iCore7 - interestingly !

Thu Aug 09, 2012 4:01 pm

I have several identical servers:
CPU iCore7-2700K (3,5Ghz 4 core), MB Intel DQ67OW, Server Lan Adapter PCI-E 4x Dual (i82576).
Servers have identical configuration.
The only difference is that one of them uses L2TP tunnels, on the other PPTP.
The problem - the server with PPTP has a higher load on the CPU. At the same time - traffic is 2.5 times less.
In the hours of highest load - observed degradation of service (reduced speed, increase delay).

1. As you can see on screenshot, for some reason the process of "firewall" has more value, even though I tried to completely disable the firewall rules
2. DDoS is not found
3. I tried the version MikroTik ROS 5.15, 5.17, 5.19 - no difference
4. Hardware is exactly the same
5. If the difference is only in the PPTP and L2TP, why the process of "Firewall" in the "top" takes more resources, not ppp / pptp?
6. What should I do? )

the answer is the same as in similar topics....

1. disable RPS
2. Manually assign IRQ
3. Select - interface queue = multi ...

All these manipulations did not bring positive results - in the evening (when most users) - CPU very high = degradate service (just something 100 Mbps of traffic).

Similar servers hardware and setting (but L2TP, not PPTP) = all rights (more than 300 mbit/s, more 1000 L2TP tunels 20-30% CPU max.)

reason of PPTP ? )))))

Who knows?

P.S. May be need full reinstall ROS - as Windows ? )))))))
