Additional Information

Slow (1.4.2) spark profile: https://files.catbox.moe/sp40na.sparkprofile

Fast-ish (1.4.1) spark profile: https://files.catbox.moe/81sb8o.sparkprofile

The slower profile now spends significantly more time in RecipeLogic#findAndHandle.

Hi, please reattach the profile for 1.4.2, I can't get it to load. Thanks.

Hi, could you try with the gtceu-1.20.1-1.4.3.jar file found in this zip and let us know? Thanks. It looks like a problem that may have already been fixed in a PR but it hasn't made its way to release yet.

Here's a second 1.4.2 profile: https://files.catbox.moe/s7ss07.sparkprofile

could you run one with a --only-ticks-over 50 in the command parameters?

so we actually see what's the laggy part

Web viewer works this time: https://spark.lucko.me/1ogovtM3kR. Seems to be generators.

This doesn't fix anything, sadly. Regular profile and 50ms profile still show the same slowdown.

Git bisect shows that the commit that introduced the regression was 05f5dd1, or PR #1955.
