XF 2.1 Large (80,000+ post) threads performing poorly after XF1->2.1 upgrade

I had to increase the PHP Max memory up to 256M for the post to even load, as it was erroring out. It loads now, but takes a solid 3-5 seconds of processing before anything is served up to the user.

Error I was receiving:
[4452] [172.68.133.113:45990] [STDERR] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /***/xen/src/vendor/composer/ClassLoader.php on line 444

Any thoughts?

Likely an add-on is doing something very silly.

I've got threads with +100000 post replies which work fine and never push member usage beyond 10s of megabytes.

Spot on as usual, sir. I of course had installed ONE addon since the upgrade and it adds some data to the postbit. I have to imagine it's doing something silly like scanning every user in the thread rather than the entire page. I'll reach out to the author.
