https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Hyperthreading-causing-system-slowdown-during-keypresses/m-p/985203#M5821 I normally don't use HT, although I did briefly when I first got my new CPU [P4 2.83ghz, and it worked fine], but I decided to use it again. When I enabled it, and rebooted a few times, it was enabled perfectly fine, with a byproduct being that whenever a key is depressed my entire system slows down for the duration of the keypress. Music, cursor, processes, everything. It also seems that when a key is depressed my CPU load jumps to somewhere around 50%.<BR /><BR />I've been using/building/configuring computers long enough to know that I can't be the only person with this problem.<BR /><BR />Any help would be appreciated.
