Memory usage after kernel update to 6.11.11-1

[b416]

I have a couple of PVE servers and just updated the kernel to 6.11.11-1 (previous was 6.11.0-2).

I noticed a drastic drop in memory usage (nothing else changed, same VMs and containers running) :





Both servers are configured the same (ZFS for data partition)...

Not complaining, just wondering what happened...

Not for me

that's very likely just ARC or other caches not yet being filled again after the reboot..

Yep, that was that. Back to old usage after daily backup this night.
