    I have a very fast machine (a 2013 MacBook Air), and under Mountain Lion, the previews of things such as JPGs, PDFs, DOCXs was instant - press space bar or cmd-Y, and the preview would pop up on screen instantly.

    Under the GM of Mavericks though, it takes 2-3 secs for previews to appear. After pressing the keyboard shortcut, nothing happens for 2-3 secs, and then the box suddenly appears on screen.

    Has this happened to anyone else? I can't see a reason for it

    I've got he same mac and it happens to me too. not 100% of the time though, and sometimes it will lag on something tiny like a jpeg, and then instantly show a huge pdf.

    same here. i'm on a retina macbook pro. preview takes way too long to open when you hit space to preview pretty much any file.

    On my (unsupported) Mac Pro, it may take some times to show the content of folders (like the Application folder). It could be due to quick look as well.

    Same here. I thought it was just me, but there might be some performance problem with it.

    I'm seeing this as well, on a retina Macbook Pro. Good to know it's not just me.

    Same problem here on my rMBP. Sometimes I even get to see the beachball for a second. :mad:

    same issue on iMac late 2013... The very first quick look in a while takes like 2-3 sec to show up, then the others are instant.

    Till you repeat it again later, then it's slow again. Definitely a bug, never noticed this issue in 10.8.

    I no longer have this issue after a clean install of the final release.

    Just piping in that I have the exact same problem - even on a clean install. Beachballing for a second, then kind of "lagging" and showing the quicklook contents.

    When searching in the Spotlight menu, photos are also very laggy when going up and down. It must be related to Quicklook or something in Finder. Hopefully someone will have reported this internally (dev account).
