All pages slow-to-open, only for some users/browsers

[Lis Riba]

Running Confluence 4.3.2

Every time I open a page under Opera, there's a 5 second delay after the page loads before I can actually interact with it - click any links or even scroll the page. It's like the entire browser locks up for those 5 seconds.

Checking the network log, the delay always occurs waiting for response on a GET request for

http://confluence/s/en_GB/3391/c989735defd8798a9d5e69c058c254be2e5a762b.36/819ac0d399862a49dfde5157822d7017/_/download/contextbatch/js/editor,macro-browser,-viewcontent/batch.js?trycatchwrap=true

When I open the same page in Chrome or Firefox, the page loads without delay.

I just sucked it up, assuming the problem was an unsupported browser, HOWEVER, I just witnessed another user experience this problem under Firefox.

Any clue what's happening and/or why it only affects some users/browsers, and (more importantly), how to fix it?

Hi,

Unfortunately I believe the problem is indeed the browser incompatibility as of the supported platforms page: https://confluence.atlassian.com/display/DOC/Supported+Platforms

If you have experienced the same in Firefox, then you may want to check if it is a supported version of the browser, also disable all browser plugins and antivirus software temporarily on your client machine to see if the issue persists. If it makes no difference, I'd go to debug it based on the following article by enabling profiling: https://confluence.atlassian.com/display/DOC/Troubleshooting+Slow+Performance+Using+Page+Request+Profiling

If the above does not help, I encourage you to open a support ticket with us at href="http://support.atlassian.com%20">http://support.atlassian.com where we can help you to debug this issue.

Kind regards,

Peter

The fact that we're seeing this in Firefox, Chrome and IE suggests that this is not a browser incompatibility issue.

We observe the same problem for one of our customers. All browsers seemed to be affected.

Any news on that? Did you create a support ticket?

As far as I know Confluence 4.x shows these problems. Does anyone know if this problem still exists in Confluence 5.x?

Do you have Gliffy enabled on your Confluence instance?

This issue - https://jira.atlassian.com/browse/CONF-27796 suggests that it could be related.

We have Gliffy installed on our environment.

I don't suppose you ever found a solution to this question? I'm seeing exactly the same behaviour in all browsers (Chrome, Firefox, IE - haven't tried Opera) connecting to my Confluence 4.3.7 instance.

Users are starting to get shirty with the performance too. :-(
