I’ve synced fulcrum a while back on (not on umbrel) there was dm_mem setting that would speed it up a lot.
Today my fulcrum went from 70 to 73% in about 24h.
I think this setting should be exposed somewhere or be set dynamically based on ram available.
I have it on a 32gb machine and I suspect it’s using the 512mb default.
