We are trialing a new kernel on our web server. We were running 5.13.19 however it is past end-of-life upstream. We attempted 5.15.x but the performance of this kernel was garbage. However, I’ve tested 5.16.0 on my workstation and it performed much better than 5.15 and at least on par if not slightly better than 5.13, so I’m giving it a try on our web server (the most heavily loaded machine). If it holds up we will be upgrading all the machines next Friday the 21st between 11PM and Midnight.
If you notice any difference in the performance please let us know.
