First of all... the 1365 simultaneous users is an all-time high. Secondly, we would have crushed the old server once it got over 700 or so. This server didn't even blink.
Now I can leave to go to games and not worry about turning a bunch of features off so that the board doesn't crash under the pressure. I can run maintenance without having to wait until 4am when traffic is low. Heck, I reindexed the entire SR archived site yesterday ( a busy day here traffic wise) which is server intensive and the effect on performance was nominal.
Less headaches is a good thing, and this new server package is definitely worth it.
