    I'm using Final Cut Pro X in my nMP and have a question regarding to its performance.
    I use 1080p AVCHD video files and I know that the performance is less with that format, so thats the reason why I let FCP X convert them in Apple Pro Res.
    But I still have jerking/lagging and its not running smooth as I saw reviews on Youtube.
    I have also to say that the video files are on the integrated SSD in my nMP.

    Do you know what the reason for the poor performance could be?

    1) Verify Disk through Disk Utility. If there are any errors, repair through recovery partition.

    2) Try restarting with the option 'reopen windows when logging back in' disabled.

    3) If all that comes out fine and restarting hasn't resolved the issues, check your SSD's health by using SMART Utility. Anything other than passed means you need a new SSD.

    4) If that's all good, try repair disk permissions and restart again.

    5) Check for OS updates.

    Yes. OS X 10.10 Yosemite. Worst system Apple released in a long time. I don't have nMP. But that is the first thing that comes to my mind. I really suggest trying 10.11 El Capitan Public beta. I have already reported that changing from 10.10.4 to 10.11 completely removed random restarts of computer that were connected to discreet GPU in Macbook Pro mid 2012.

    In addition of the above good advices...
    Is your ssd full?
    Are you running any other applications at the same time?
    IMHO I think it's also a good idea to add more RAM if you have only the stock 12 gb.

    I did all advices and everything seems OK. I also did the LONG Smart Utility Test and that was also fine.
    I really don't know where the problem could be. Perhaps a clean install of the system?

    I don't know adding more RAM will solve the problem because I'm making short clips about 10 minutes and don't use much effects.

    Even if you're running out of RAM and it pages to the SSD, the speeds of SSDs means that you really shouldn't be seeing performance dropping as you are. This is a tricky one.

    When it's beginning to lag, would you be happy to screenshot Activity Monitor?

    So here are the screenshots.

    I have aslo to say that its lagging when I go through the clips which are NOT in the timeline (lagging when clips has to be draged in to the timeline).
    It's also lagging when I zoom in or out or edit a clip like cutting.

    Not sure what the first image was suppose to be but the CPU tab in activity monitor is indicator that it isn't CPU workload. Temporary blimps in responsiveness though are more likely RAM relative ( high memory pressure as indicated by modern Activity Monitor) or Disk I/O spikes. Those are two other tabs.

    A screen capture of those two relatively shortly after experiencing a lag would be the most informative. Get lag. Switch to Activity Monitor and look/capture.

    All of this ProRes conversions is done batch long before you start editing right?

    Yes, the conversions were done before I started to edit.

    The screenshots were taken when FCP was lagging and the loading round ball was shown instead of the cursor.

    Yosemite does much much better if it was a clean install and not upgrade, as well as fewest possible add'l background apps and processes as even one incompatible such task can affect performance.. even those handy monitoring apps.
