    I experience slow/partial web browsing after upgrading from 10.6.2 to 10.6.3 last night 3/29

    Some web sites without much graphics will work fine and fast (e.g.,, yahoo mail, wikipedia, outlook web access from work), but others will start loading but never complete loading (e.g.,,, are loading forever)

    This happens on both Safari 4.0.5 and latest FireFox 3.6.2.
    This happens whether wired or wireless
    I have shutdown several times, recycled both cable modem and wireless router, emptied Safari Cache, not to avail.

    Any similar experience? Please help.

    Have you tried and maybe have comparative results from an earlier speed test?

    The internet connection doesn't seem to be the problem... as other computers are working fine.

    I just tested on and I get a decent down/up speed of 9.02 MB/s / 0.49 MB/s

    Try clearing your cache to see if that helps. Also download a different browser like firefox to see if the results are better.

    I´m having similar problems but in my case, safari and Google chrome browsers unexpectely quit and the reason was that the browsers were having problems with the flash content... this beheavour happened with my Imac i5 27" and my MacbookPro unibody 13" after installing 10.6.3

    I experience the same problem, may be on different sites, but still.
    Very slow loading of pictures and other elements, especially if site is complicated, working on CMS, like Joomla or others.
    And the problem is complete the same on both Safari 4.0.5 and Firefox 3.6.3.
    It started after 10.6.3 Mac OS X Update.

    I solved this problem by moving from Safari 4.0.5 to new Opera 10.52 for Mac.
    On Opera 10.52 everything is working fast. I love Safari, but 10.6.3 Update was very disappointing.

    10.6.3 is Slower!

    I also done benchmarks, my computer is noticeable slower with 10.6.3, on startup and shutdown, already done cleanup, something in the 10.6.3 code that Apple needs to fix, fast! I also tried Ubuntu 10.04 LTS on my computer, and heck, it's twice as fast as my Mac OS X, so much for Snow Leopard deep optimizations :(! Just wish Apple don't forget Mac OS X now that news are only iPhone/iPad relative!!!

    Same Problem

    My Wireless N syncs to an Apple TV are now 40% slower than under 10.6.2.
