Why does encoding seem to significantly speed up after a reboot?

    Has anyone else ever had a very long estimated time for an export, tried rebooting the computer, then found it goes at a normal speed?

    Why is this? What is accumulating that slows it down?

    Because a restart clears all the RAM. To save time just open Terminal and type in "purge." It does the same thing as a restart.

    Intel Turbo Boost?

    You can view the Turbo Boost status with this utility:

    I don't think that's the case, I have 16GB RAM and will have a decent amount of free RAM while exporting in Premiere Pro CC, then the reboot speeds it up.

    Likely you have some processes running that you don't know about an the re-boot sops them. If you knew about them then you could do this manually. Have you kooks at Activity Monitor both before and after a re-boot? Look at what is running and amount of RAM used.

    I don't see a difference on my iMac but then i'm car full not to run other software while I'm transcoding video.
