So, I run this small server and want to run the mindcrack pack, but the server runs incredibly slow when running the pack whereas it runs smoothly while running FTBBetaA. It appears to be serverside, as when I try to do things in the console, it takes several seconds to register and the block lag is immense (multiple block break attempts required). Nothing obvious appears in console and the only mod removed is soul shards due to some strange incompatibility issue.
