Title: Burst of packages causes slowness
Post by: Sprudeldude on February 23, 2026, 10:33:51 PM
Hi

Lately i'm experiencing slow loading speeds on casual browsing.
When i check the "Health" dashboard and filter on "Packets" of my LAN network, i'm seeing this spikes of "inpass" & "outpass" packets.
These spikes are at the same moment as i'm experiencing the slowness.

The amount of packages, between 4-60 million package looks way too much? As i see earlier in the graph it should be between 100.000 and 500.000 and experiencing no slowness.

Can Opnsense help me further to track down what is causing these spikes?

Kind regards

Go to Reporting > Traffic

There you have live graphs that show pps, bps, throughput per host.

Choose all your interfaces and observe which host is causing this.

Thank you for the response!

Is there any history of it?

Those are only live graphs.

If you want to keep some history statistics you would have to implement netflow.

Adding: If the system is having load issues already, Netflow may not be desirable. In fact, have a look at "Reporting: Insight" to see if it's already enabled. It is configured (naturally) under "Reporting: NetFlow".
