It’s been awhile since I’ve used HAProxy (changed roles, loved the product). But are there drawbacks running on all cores? I seem to remember sticky routing and acls not working properly as each core had its own set. Has that changed?

You probably remember the nbproc [1] setting which indeed is multiple, unrelated processes. There's proper threading now (since 1.8).
