It’s not just a Windows thing. On my FreeBSD system it swaps between CPU
cores too. I see this with any long running process that drives up the
CPU load. eg: while compiling with FPC, running unit tests, compiling
INF help etc. All these are single threaded applications. Long running
processes that sit idle are not moved between CPU cores (or so it seems).
I have an Intel i7-3770K with 4 cores (8 if you enable hyper-threading).
I monitored the running process using “htop” and “Mate System Monitor”.
