We have one of the best hardware setup's going it's nothing to do with the hardware we are running on, all these false assumptions are really irritating. The current problem we are facing is PermissionsBukkit, we have over 30,000 Players set-up in a yaml file, this is crazy. We are hoping to migrate to PEX as the data can be stored in a MYSQL data base, all the rank changing and such is causing lag because the file is getting bigger. We plan to fix this soon, but it'll be hell of a job.
