23.7 Legacy Series / Re: CPU Performance after 23.7 upgrade

« on: August 08, 2023, 05:35:01 pm »

Hopping on this thread to report asinine CPU usage in the gateway_watcher.php script post-upgrade to 23.7. Configuration did not change from 23.1.There's absolutely no reason this should be using orders of magnitude more CPU time than suricata, ever.  Both primary and backup systems show the same behavior.

Intrusion Detection and Prevention / Re: IPS interferes with internal LAN traffic

This is absolutely a problem with suricata on 20.7. All traffic comes to a standstill in IPS mode, CPU utilization drops to 0% (occasionally enough packets get through to see the CPU graph). I know it's a problem because the exact same system ran 20.1 for a year with suricata in IPS mode with no issues at all. This isn't a performance issue, it's a thread-locking issue or something similar.
