It has come to my attention that a lot of people have been experiencing slower than normal operating speeds for Traktor following an upgrade to Lion on the Mac.
I have not been experiencing these issues on my 2006 MacBook Pro, but I have been noticing some lagging on my 2010 iMac whilst using logic, which should not be the case. The only real difference I could imagine was to account for this speed difference was down to the fact that I had previously completed a clean install of snow leopard on my MacBook Pro just a few weeks prior to upgrading to Lion. My iMac on the other hand had simply gone through normal computing with no clean installs before merely upgrading to Lion.
Taking this into account, I searched for some advice online and found the following article recommending that I boot into recovery mode and repair both the disk and the disk permissions. I followed these instruction, then restarted and did nothing with my iMac until the spotlight had indexed the drives. You can check to see if it has finished indexing by simply pressing ‘Cmd’ & ‘space’.
This whole process took about 30 minutes and didn’t involve a clean install, it only found 2 or 3 permission errors & no disk errors, but following the advice, I repaired anyway.
Following reboot, and completion of spotlight indexing, I started up iPhoto with a 12,000 photo library, pixelmator, which had a large project in that was lagging very heavily the night before, logic, with lots of plug ins and Final Cut Pro X. I ran them all together and all ran seamlessly.
I would certainly try this out as your first attempt to fix these speed issues. Hope this helps.

If this doesn’t fix your issue, I would suggest the next step to be a clean install of Lion.
