Hi --
When I try to open a page on LinkedIn in Firefox or
Konqueror, it takes forever to display. Often, the
session times out before the page is shown. I have
not noticed any other sites which have similar problems.
A Google search shows that a number of people have encountered
similar problems. There were conjectures that the problem
has to do with routers or network settings. There are a few
suggestions to reduce the TCP MTU size, and some people
claimed this fixed their problem. When I followed these
suggestions, it doesn't improve display of LinkedIn pages,
but it did screw up display of other sites.
On a Windows XP system running under VMware on the same
hardware, Firefox displays LinkedIn pages with no delay.
Since the network connection and router is the same,
it's not a problem with the physical hardware. Since
the same problem appears on both Firefox and Konqueror,
it's not a problem with the browser display engine.
Anyone have a suggestion how to eliminate this annoyance?
MTU sounds good, the usual "real cause" is some router not passing or honoring
the "can't fragment" ICMP. If you are running from a VM, behind a tunnel, etc,
etc, this might be your problem, and since there's a simple solution it's worth
a try.
Look at the "mss M" section of the "man route" output, and it explains this
better. Using the route command you can set a route to the problem site, via
your default router, and only for that route use a smaller MTU. So "mss 1400"
would be part of the command line.
I learned that so long ago I can't remember details, but the capability is
there. Let us know if it helps.
