XF 1.4 Performance woes - sluggish on some Macs, and slow on PC

    There are Mac users who can't stand the sluggishness, as well as scrolling issues. Its not flickering (something reported with OS Yosemite) but choppy. I haven't tried on mobile (I don't have a mobile device).

    So I ran a GTMetrix scan, and here are the results.

    The PORTAL page is a WordPress installation (different database).




    The Xenforo FORUM is here:




    I'm a bit lost (OK I'm clueless) what to do with these settings. Anyone has knowledge and experience? I see a few things that seem worrisome, like Expiry headers, Gzip compression, defer parsing javascript, images sizes (when I check the ones mentioned they are quite small so I don't get this one).

    Anyone knows of a set of settings I can do via my CPanel, to improve this poor performance? We have a few million posts and over 10,000 members, although the attendance has dropped dramatically since the conversion.

    So I'd like the performance to NOT be a deterrent! :)

    BTW, is 1.5 bringing anything more to the table in that department?

    Thanks a bunch!

    What webserver are you using?

    Odds are, since he said cPanel, it's Apache. Few splurge on the option of LiteSpeed.

    Since you are using (most likely) Apache, you need to get REALLY involved in tweaking it to the max. You could always get a LiteSpeed license and use with cPanel - or if you don't need a panel use NGINX. Mine is running in SSL mode if you notice - but I'm still getting a 97/81 score.

    Your problem has nothing to do with your webserver, you just need to remove the fixed background (on the portal) and the fixed header menu (on your forum)

    Actually yes, the hosting tech support could not access the site themselves via SSL and had to reboot the server.

    And the member who had issues wrote this morning to let me know his problem went away, so great news in the regard.

    Ahemmmm... mine has a fixed background also.... so that doesn't (on the XF side) have that much to do with it... the issue is that the server needs to be optimized for the HTTP configs.
    A simple image won't cause that kind of problems... otherwise there would be loads of people having issues.

    It all seems related. I actually started looking into a new hosting when this Mac issue came up, I had suspicions...
