I have a question about FCPX

I Film Weddings and Edit in FCPX, the problem I have is After I have add about 1hrs worth of footage on the time line the system slows down to a crawl, and its driving me crazy.

I have a iMac, 3.5Intel i7, 32gig Ram, Flash Drive, Lacie Big 5 Thunderbolt 10TB drive.

Back Ground Render is off, PlayBack set to Better Performance not sure what else i can do.

Should i be working in Proxy File mode ?

Regards Robert.

Turn off waveforms and thumbnails in the timeline and see if that helps.

I just edited a special project with two 120 minute video files in the timeline and FCPX was grinding to a halt until I let the waveforms and thumbnails all have time to be generated. Unfortunately I needed them in this instance and unfortunately there is no indication in the background task window that anything was going on behind the scenes in the program, just the spinning ball. Once the program did what it needed, it ran smoothly.

Robert, do you have any effects applied to the videos? I use the LUT Utility and it has a memory leak that causes the RAM to climb until FCPX freezes. The (temporary) solution for me is to close Final Cut before it gets to that point.
