    Hello, I tried public beta on my iMac 2012. High Sierra is so slow that I can't even use it. Booting takes 2 minutes, opening stock apps takes around 30 seconds. Everything is so laggy, when I hit search field it takes few seconds until I can write into it. Im on El Capitan now and everything runs just perfect, my computer boots few second, opening apps is so fast that I cant even notice it.

    I know that its beta, but why is so slow? My computer has more power than some new Macs - Macbook, curent MacBook Air etc. Hows beta running on that computers?

    Running the public beta on an old 2011 MacBook Air, and I'm having the same results as you. Very slow. Not unexpected, because it's a beta, but I'm sure they'll iron the kinks out before release.

    The first (Public) beta is always slow and buggy. If you can wait a few weeks, beta 2 will likely fix 90% of issues that pop-up in the initial version. If you can't wait, use Time Machine to roll back your install to Sierra (or whatever previous OS you had installed). You do have backups, right?

    Running on a 2012 MacBook Pro. First beta was a little slow to boot compared to Sierra. All apps fine and opens fast. Beta 2 see's a fast boot and normal app speed.

    I have noticed on my 2010 MBA that spindump and tailspin are running often eating considerable amount of CPU time. Anyone know any fixes, how to prevent them from running?

    It’s better if you wipe your Mac clean and set it up as new. I put High Sierra on an old 2010 MacBook Air and it was unusable until I wiped it clean. It was still slow and laggy but the crashes went from every 5 minutes to every 2 hours.

    Hard disk drive, solid state or hybrid?

    APFS?

    Same issue with MBP mid 2010 with i7. I tested this with noSSD drive and 4 GB of RAM, super slow, even opening "bout my mac" took 20 seconds. it was a bit better with HPFS, but nothing close to a 10.12 experience.

    I am planning to test the newer beta release with 8 GB RAM and SSD in the same machine, I am hoping for some progress.

    Yes, similar problem on a late 2016 MacBook Pro. Please open a bug report with apple.
