Large Alias Causing CPU spikes and ping latency

[guenti_r]

We were testing with this regarding the kernel panic issue:

# opnsense-patch https://github.com/opnsense/core/commit/c8497ac14603

It needs a cron apply or reboot.  It will only reload the aliases twice per hours at the expense of the update interval. It has downsides, but we were discussion making it configurable for some edge cases like this.

Is this patch compatible with 25.4 ?
We really need this to made it configurable. In the meantime, the 1/31 would help us alot.
One of our customer has some problems with the constant minutely latency spikes with VoIP.

Here we have similar aliases (about 150) with average 3 million entries.
Reducing these to 50% does not help, the latency spikes are still there.

Hi,
I've put my hack in a PDF for other to use. Please see attached. It works for me and the CPU load is now totally gone.

Waiting very long now, when will this be fixed?

These latency spikes exisit up to 25.10.1_2

Spikes will exist always based on setup. If you refer to code changes related to reducing spikes I suppose you're already running all the relevant code changes on 25.10.1 too. Details matter. Asking for blanket solutions on 6 months old threads isn't going to achieve much IMO.
