Status: VERIFIED DUPLICATE of bug 70213

(Core :: Networking, defect)

Description

[Dr. Werner Fink]

Mozilla version 0.9.5 end less:
Open several windows and try to open a further
frame with a new URL blocks redraw of the older
frames during DNS lookup/resolve depending on
the new URL.

I am unclear about these steps to reproduce. Can you please give a clear set of
steps and the actual and expected results. Thanks.

Open a new mozilla, goto a web site which provides
a huge list of different URL's.  Now open some of
those URL's with the middle button of your mouse
(Open in a new window).  What I get are new windows
whereas the old window is unusable during DNS lookup.

If DNS lookup gets success all windows are back for
usage, nevertheless sometime resolving a domain name
requires a huge amount of time.

You can add one important thing.

If the DNS are down or the lag too long, ALL mozilla windows freeze until the
address is resolved.
If you use the bookmark notify fonction with a lot of web site and a lot of
different address, Mozilla freeze itself when an address couldn't be resolved or
takes too much time to be resolved.

I find this annoying, too.  Another place where this is exhibited is an online
message forum that allows inline pictures, such as one powered by zeroforum (ie
www.corvetteforum.com -> forums).  Each message thread can have inline images,
which must be hosted somewhere other than at the forum.  So, each message thread
(page) can have many images, each of which needs a DNS lookup.  If you open
multiple windows, each with a different message thread, many DNS lookups occur
during the loading of the images.

Example:  from a message index page, middle click on several different threads
with images (indicated by the camera icon next to the message thread title) to
open each thread in a new window.  When the DNS lookups are occurring, it's
impossible to scroll in the first window, screen updates are not performed on
any window, etc.  If you have a slow/busy DNS resolver (like my place of
employement), this can become annoyingly slow.

No CPU is used by the process when this is occurring.  Mozilla 0.9.9, Win2k.

this looks like bug 70213 - only one DNS lookup can be performed at a time.
