    Hi,

    I've recently upgraded the RAM in my iMac from 4GB to 12GB as it was running a little slow, I have found this has made no difference and at times seems even slower.

    I was doing some work with video files and was converting a video using MPEG Streamclip and so this would be quite a memory intensive task. As it was progressing very slowly I checked my Activity Monitor and it was only using 4.49GB of the memory and of that only 97MB seemed to be dedicated to the MPEG Streamclip task.

    Does anyone know why the system isn't using the rest of the RAM that is installed?

    The highest usage process is 'kernal_task' with 838.9MB but I don't know what that is, There are a lot of items in the process list but I don't know how to remove them or even if I can or should remove them?

    Any help would be greatly appreciated

    Thanks

    Dan

    Hello a computer will only use as much ram as it has to at any given time, so yours is not an issue with the ram; video processing is actually a CPU intensive activity, while rendering depends on a good dedicated video adapter, I don't know if your iMac has one, if not, that would not be a good thing, also unless your iMac is packing a good core i7, running around 3Ghz, you can forget about performance.
    Meanwhile, use the Disk Utility and check the permissions on the disk, those are known to hamper performance a whole lot.
