Intermittent issues with page loading speed

There is an issue with communities page loading speed from different local offices.  Sometimes portal is almost unusable as it takes forever to load any page in communities.bentley.com while other sites work correctly.It appears that the main bottleneck is that some images are very slow to load using SSL.


For example when experiencing slowdowns this image(HTTPS) doesn't load at all:

While this image loads instantly(HTTP):

  • About half the time no new page will load - stays on Connecting forever. Mostly, an existing page can be redirected (by clicking breadcrumb) to another forum OK - then sometimes the 'connecting' ones immediately connect. But sometimes even opening a post from an existing forum's front page hangs forever. Often, comment's I've typed fail to upload - no response from the Post button, no 'waiting for' message shows bottom left. Opening a post from a notification email generally works. It's got progressively worse over the last week - today it's more than half, overall. All other websites connect fine. Latest firefox.

  • That is the third instance where we have heard Firefox hanging on a forum post (either creation or accessing an existing one). Something is obviously not right there, but we really have no explanation for it (at least now…) We will look into to it to try to determine what needs to be done to sort it out.

  • Even when a page has loaded OK and is functional, the twirling symbol in the Ffox tab often shows that the page is still loading - forever - and the page refresh symbol is not available just the X to stop loading. Often the info at bottom left says it's waiting for Twitter or Google or similar.

    Redrafting what I said above - Often, comment's I've typed fail to upload - the Reply button greys out when I mouse over it, no 'waiting for' message shows bottom left, but if I click anyway and leave it long enough it sometimes uploads all by itself!

    In general, even when working, BeCommunities is about 3x as slow-responding as any other forum I use.

    Another thing about Ffox - Home and End still unpredictable Ctrl+Home works but not Ctrl+End - works sometimes with Ctrl, sometime only without, sometimes one not the other, sometimes not at all. OK with Chrome but I don't like it.

    Yes that also was observed for me. Twitter and Google also connects trough https://

    If you open this topic when you experience slowdown and click CTRL+F5 then which images loads first in my post?

  • Again was experiencing slow down. It appears that it only occurs in Firefox as opening this same page on IE works correctly. Now it was vice-versa some images trough http didn't load. Restarting Firefox solved the issue.

    Some of add-ons could be at fault as it didn't load for example translate.googleapis.com/.../hrs.swf element which is banner for google pidgin translate. Disabled flashblock and now whole page loads correctly.
