waow 50% less memory for a mimalloc -> jemalloc swap (yes that is under-3G-rss while backfilling)

I did something similar, I dont think moving lots of small events around threads is very efficient for the standard allocator at the rate of the firehose. Im also becoming partial to the idea of using memory arenas

yep. i saw a memory *increase* from std -> mimalloc but it did get a performance jump. but it was just too tight on this machine. this is not a benchmark setup but i think the mimalloc -> jemalloc change did get another small perf jump though
