We just updated from 3.14 to 4.4 Enterprise last weekend, process went VERY smooth. During this time we also took the time to upgrade to Ubuntu 12.04 running on 64 bit OS as well. Only issue we are seeing is that our reload times have gone up almost a 60 seconds. We a master server, db server, 21 slaves.
Has anyone seen anything like this or have a recomend to try and bring it back down?
