Oh sliding in here late, but it’s also extremely important to pin your threads to specific cores. I kinda only think about computers in this mode so I didn’t bring it up, but the kernel will effectively randomly schedule your process to different physical cores. If you are doing intense IPC or otherwise relying on specific cache usage, getting assigned to a different core is a massive loss of existing state which takes time to recover from!
