Load Balancing - CPU Load

RouterOS General
1

Hello,

I purchased the router RB2011UiAS-2HnD-IN
I configured the PCC Load balancing - http://wiki.mikrotik.com/wiki/Manual:PCC with 3 WAN connections (3 ISPs).

The Load balancing is working pretty fine but the CPU load is at 90% which is a little bit too high.

I tried the ECMP Load Balancing with masquerade - http://wiki.mikrotik.com/wiki/ECMP_load_balancing_with_masquerade
I tried also the Load Balancing over Multiple Gateways - http://wiki.mikrotik.com/wiki/Load_Balancing_over_Multiple_Gateways

The CPU load was also at around 85-95%

I installed the latest upgrade pack 6.11.
The firmware version is 3.08

Does anyone have an idea how to reduce the CPU load ? which load balancing script can be used ?

just extend your cpu Randam Access Power and also check your processor heat sinker

smarthunter, may be it’s a stupid question, but how can I do that ?

4

how much traffic is going through this?

5

around 200 MB/s constant download and 20 MB/s upload
2 ISPs with 100 MB/s and a third one with 30 MB/s

That sounds about right for what you are doing (mangle rules, filter rules, NAT rule). Here is the performance test for the 2011 series:

Agreed.

honestly I know it was over kill but for all my PCC setups that I was seeing 20,000 pps or more per interface I just went with the CCR 1016. I have like 8% max cpu usage.
