Fast start times are a valuable thing for a service component.

Stick about 10GB of small entries in it (should be enough to create all the levels) and then see what happens.

Also, you could reserve the persisted [H|T] for controlled shutdown scenarios. Basically anything that isn't complete system failure if you're properly trapping signals.

I added some more benchmarks including packing with 200M small 64 byte messages (20Gb) and consumption of that queue. There is no slowdown because of mass delete. https://github.com/bogdanovich/siberite/blob/master/docs/ben...
