I've noticed FCPX has slowed down it's opening sequence significantly on my nMP (25 seconds). I'm on a dual monitor setup, 8 core 32gb, and my current project is maybe 20-30 seconds long. Any ideas? EDIT: OK, now I'm just confused. I created a new library and hid all the others and moved them out of the movies folder. Still had the hang. However, out of desperation I pulled my SD card from my camera and plugged it back in and presto- FCPX starts up in 2 seconds now. Mind you, I never imported from the card- I always copy over any media to my HD, then import to FCPX. EDIT 2: One more piece to the puzzle before I quit for the night. The SD trick I mentioned earlier only works for the first few minutes- then FCPX returns to the 25 seconds startup unless I eject and reinsert the SD card. I've deleted all my libraries and events, I've deleted the 3 pref files, nothing. I've created a test account, and FCPX runs lightning fast on it. Guess I'll reinstall while I sleep, but I'd love if anyone had any other advice!
