At the risk of inciting a flamewar, I was curious if anyone had some recommendations concerning a php accelerator when it comes to wordpress mu. I currently run the most recent eaccelerator, but there are some old posts here concerning some potential problems between it and wordpress mu. This seems odd, since it sounds from Donncha's blog as if he's running eaccelerator, so I would take for granted that eaccelerator is a good choice for a server running mu.
