Minor quibble but: probably get another 5-15% by upgrading from oldoldstable Debian 11/Bullseye with kernel 5.10 to something modern like Debian 13/Trixie.

Edit: oh these are containers, right; the difference will be far less since the kernel is determined by the host. Still, I find it sad to see old software versions like this used.

Thanks.

I re-used all scripts and didn't even notice the linux version.

For the on-prem/homelab crowd: I upgraded my desktop from Debian 12 to 13 yesterday only to discover my Mellanox ConnectX-3 NIC wasn't supported by the Trixie kernel. From 10GbE to 0GbE in one reboot :/

Have ordered a ConnectX-4 so that should get me going again, of course 100GbE is severe overkill for my needs but since I already have a 100GbE switch I figured why not...
