Hi, No, I wasn't even aware of it. Searching my systems for wikidiff only turns up includes/diff/WikiDiff3.php in the MW code. I can try testing wikidiff2 by installing the php-wikidiff2 package and seeing if that makes a difference.

Here's an example excerpt from the FPM > status page with the pool info and one of the hung processes: Do you have the wikidiff2 PHP extension[1] installed? If you're having performance problems with diffs, switching to the C-based implementation should help. Diffs of that size are going to be large regardless, so I'm not too surprised it's having issues... I'm not familiar with php-fpm timeouts to give advice on that, sorry.
