Epsilon tied on speed but lost to Shenandoah on latency because never freeing memory isn't ideal either, even if you never run out of memory.

Ya if you allocate/deallocate onto a stack, the most recently freed memory is more likely to be hot in the cache for the next allocation, reducing overall latency.

It’s something I do all the time in C++.

It'd be interesting to see a version of that graph with just Episilon/Shenandoah. It's hard to tell but it looks like Epsilon may actually have lower average latency but Shenandoah may have lower jitter & max latency.
