High CPU usage under stress, not entirely unexpected - testing opportunity?

[evilantishad0w]

Versions
OPNsense 24.7.6-amd64
FreeBSD 14.1-RELEASE-p5
OpenSSL 3.0.15

Intel(R) Celeron(R) J4125 CPU @ 2.00GHz (4 cores, 4 threads)
8GB memory

This installation is supporting a dozen "kiosks", displaying a variety of sites, including several video streams. Average throughput is 20 megabit, peaking at 100 megabit. I'm seeing usage spikes on the CPU graph, occasionally above 30. This is I suppose to be expected, considering how anemic the CPU is, and I'm fairly satisfied with the performance. Even so I think it may be a good testing environment for code profiling. If anyone is interested in specific logs or for me to install a profiler please let me know.

More info:
Intel QuickAssist Technology enabled w/ not much effect
PowerD disabled
Interfaces Settings: Hardware CRC, Hardware TSD, Hardware LRO all enabled, not much effect
Using pure IPv4
"Firewall states" widget removed from home page (seems to cause system stress)
CPU temps low, ~40C, so spikes must be very short duration
