Internet speed is very low when ‘node-0’ is the master and the internet speed is fine when ‘node-1’ is the master

This article describes the issue of the internet speed being very low and CPU utilization being high, when node-0 is the master; whereas the internet speed is fine, when node-1 is the master.

  • The internet speed is very low, when node-0 is the master; whereas it is fine, when node-1 is the master.
  • CPU utilization is very high, when node-0 is the master.
  • When node-0 is the master, the speed is around 2 Mbps and when node-1 is the master, the speed is up to 45 Mbps.

This issue is due to high CPU utilization on node-0.

In the output of show system process extensive, the av_worker process is high.

Output:

When troubleshooting the throughput issue, perform the following procedure:

  • Check the CPU utilization.
  • If the CPU utilization high, then it has to be brought down.

In this case, CPU utilization is high due to the av_worker process. Perform the following procedure to reduce the CPU utilization:

1.De-activate the security UTM:

2.De-activate the reference of the UTM policy in the security policy.

3.Commit.

4.Run the following commands:

5.Commit.

6.Now activate UTM again:

7.Activate the reference UTM policy again.

8.Commit.

After the above procedure is complete, the CPU utilization will come down and the internet speed issue will be resolved.
