Memory management different 24.4.1/24.1.9? Or Intel/AMD?

[Greg_E]

I set up my business version yesterday, and while it initially showed a huge amount of RAM in use (over 7gb or around 50%), it is now down to 34%. Old system was normally around 45-47%

Old system was AMD V1756B with 16gb and an Intel i350 card. OPNsense 24.1.9

New system Intel Xeon E3-1230v5 with 16GB of ECC ram and 10Gtek i350 card. OPNsense 24.4.1

Both were running IDS/IPS, Crowdsec, Zenarmor (free), and a DHCP server pointing to a fifth port. Rules and exceptions were copied from one device to the other so they should be at parity for features.

Is this a business optimization or and AMD to Intel optimization, or just an oddity? The only software difference was the Realtek NIC driver for the AMD device, since it had a single Realtek NIC that I was using for a "management" port with a laptop as needed.

I'm certainly not complaining, but sometimes you just have to ask why this might be happening. This Intel based version does seem to "run" faster, sites complete loading faster and the GUI performs better. But the CPU scores for both single and multithread are fairly close, so I would have expected similar performance. I did verify that the Intel branded cards I bought were real genuine Intel, not the counterfeit that are available.

Doubt it's anything more than termporary processing of lists/aliases/rulesets in Crowdsec/ZA/Suricata

The AMD system started at over 50% and eventually worked down to 40-45% so I was kind of surprised that this Intel was lower.

Some of that might be skewed because the AMD system had "less" total memory, some was used for the GPU, but not enough to really make this big of a difference.
