Quick update: DFINITY plans to propose two distinct replica versions today. One “standard” one and one targeted at improving the situation on busy subnets. This version includes similar scheduler changes as I mentioned in the first post on this thread, and which caused a slowdown on the first busy subnet fuqsr this week. We believe comes from memory contention in the replica, stemming from the fact that the modified scheduler rotates more quickly through all canisters. In this week’s version, we include additional changes that should help prevent this memory contention. Hopefully we’ll see improvement from that next week, and the dfinity team is still working very hard to further improve how the replica handles high compute load from many small messages.
