Safari Hangs, then eventually loads page

Safari 5.0.1 or later: Slow or partial webpage loading, or webpage cannot be found

Same issue here on an iMac running Mountain Lion. Can take up to minutes to load a page... sometimes the page won't load at all. Tried the DNS prefetching disabling -- no effect. I highly doubt it has any router involvement, because as I waited for the page to load on my iMac, I found my phone (iOS6) and typed in the same web address and watched Safari on my phone load the page in about a third of a second. I then grabbed my Macbook (running Lion) and did the same -- page loaded in about a half second. Grabbed one of my kid's iPad (1) and watched the page load in a couple seconds. And as I type, the page still hasn't loaded on the iMac...Suggestions?

Also, when this happens (because sometimes Safari loads the page extremely fast), I notice that my mail will load slowly as well; if I'm listening to internet audio, it will frequently interrupt....

Me too. It's not a router issue. All of my Windows, portable devices and pre-Mountain Lion Mac's do not have this issue. I've also launched the developer console and watched the requests -- the whole time I'm waiting, it really looks like Safari is doing absolutely nothing but spinning. Sometimes stopping the current request and refreshing will finish loading the page immediately, but not always.

This has been happening for a few months now -- very annoying.

I'll add to this. Safari loads between 25 to 50% of the page and then just sits there. On my iPhone or iPad there is no hang time. What gives?

Mine did this a month ago after downloading SW update. It did this for about a week then "bingo" it came good. Could Apple have corrected a bug???
