@ianthetechie @feld I can confirm that #Python on #FreeBSD behaves as one would expect. It consumes all RAM (with #ZFS releasing ARC as expected) and then dips into swap. As soon as Python releases memory after the ingestion routine, the swap is purged to near zero and the RAM then becomes available (and used) by the system. Far more predictable and reliable.

If you have big, vertical workloads, FreeBSD is where it is at.
