If the > issue is throughput IMHO the answer is to swap to multiple devices. I thought the idea here is if your swap is not redundant and it goes away the system crashes (or otherwise misbehaves)? I used a beefy poudriere build server (48 cores, 192G, 6 x 480GB nvme) and I build > 1000 packages daily. I see lots of build failures (usually 2-3 a week) but instead of core dumps I see "Killed" in the poudriere logs. Appended is one from today. (Not sure what's up with the symlink failure at the very end...)
