Didn't have this problem before - minecraft slowing down every few minutes - basically goes to a crawl for maybe 30 seconds, then back to normal. I've uninstalled & reinstalled Java (32 and 64 bit) and minecraft. Played with settings (even on lowest it does this - again, this computer is more than capable of minecraft and used to handle it easily). No luck on all fronts.
Any ideas?
