Forum Page rendering fast but browser "Transferring data from"... For 10 seconds more
 

I have a strange behaviour on my site:


Browser (IE8 and FF) are showing "Transferring data from (url)" ("Waiting for.. " in IE) and progress bar for another 10 seconds or so after the page has renderd down to the last html closing tag.

• I can see the page renders in arund a second and can open source and see the closing tag. But the Waiting for and progress bar are still there for about 10 seconds.
• FF PageSpeed does not see the last delay, but indicates that all is OK.

This happnes both over the web and on a browser on the server, so it does not seem to be a networking issue.

It seems to me like the browser is waiting for some transfer completed message which is for some reason delayed.

It is more on the to page for the forum and blog not the CMS pages. Subpages and forum threads render and finish quickly. I suspected som statistics wher written so I disabled most stats I can find.

Running 4.0.4, did not notice the prob on 4.0.3

It does not make a difference if user is logged in or not.

I have reset cashes, counters, rebuilt. Enen rebooted server.

The site is low load (2000 pages/day) on a dedicated 3.4GHz quad core server.

CPU and mySQL activity remains low also in the "delay" periods.

Any ideas what I should look for?
