I am using RB3011 with two ISPs 140mbps + 105mbps. Router was running 7.1 stable and now 7.1.1 stable. However, with just 245mbps of load balancing the CPU usage increases to 75-85%. Earlier in v6 it was 35-45% maximum. Kindly check my PCC configuration and point out if any of my mangle rules are cr…

Second, unless something has dramatically changed about the essence of fasttracking in ROS 7, packets belonging to fasttracked connections bypass mangle rules (and other processing steps not relevant here). So to have fasttracking and load distribution work together, you have to allow only connect…

Yes!!! it is lot less like with 140mbps it is 20-30% max. That sounds as if disabling the mangle rules was disabling something else (connection tracking?) as well, so post your complete configuration (hide-sensitive is not necessary any more in ROS 7, the rest of my automatic signature remains …

RB5009: 2 wan 1gb+ 500mb pcc about 80% cpu use.

Here is my config: As expected - when the mangle rules are disabled, connection tracking is deactivated because enabled under ip/firewall/connection/tracking is set to the default value auto, and therefore connection tracking is only activated if at least one firewall rule refers to metafields …

My understanding is that there is no “Route Caching” in ROS7, hence the jump in CPU utilization from V6 to V7.

This post is getting confusing. Seems like V7 has made some changes under the hood that need to be better explained.

This post is getting confusing. It’s because these are two separate issues. One is the impact of connection tracking being activated by the addition of the load balancing rules (something you normally do not notice if the default stateful firewall is in place, which is not the case here), and …

The other one is the impact of the absence of routing cache in v7, which has been mentioned multiple times here and there, but does not explain the difference in this topic. Then why is ip route cache option present in ip>setting?

Very high CPU usage on PCC Loadbalancing with 7.x

I am using CHR v7.2 RC1 with AMD athlon 200GE and utilization is 12-17% max with the same set of rules.
