you limit in this case manually your system-load, thus possible points more to system issue. But good that these workaround works for you.

A hint about commited/used memory: you can just use the “Resource Monitor”.
Ps: not sure whether all users in thread are aware of the topic: “ctd since 1.12.13.0”
