I've been running a server for a modpack with Rustic in it and have been periodically performing CPU time profiles using the mod LagGoggles. I've noticed a performance issue which stems from Alchemy devices that have items in each slot, but are not currently brewing elixirs.
This issue occurs with both standard and advanced alchemy condensers. If all slots are full, as shown in the screenshots above, the condensers will tick rapidly and cause up to ~750 us/tick worth of lag. After testing for a bit I've found this to be consistent. If either the bottles, inputs, or fuel slots are emptied, the lag does not occur and the condensers contribute a much more manageable ~5 us/tick. If all slots are emptied, the condensers contribute nothing to the server load whatsoever.
I understand if this is difficult or impossible to fix in the short term. Let me know if you'd like any more information about the issue.
