vs2010 debug web app network activity

[gerry]

F5 on a brand new , unmodifed web application in vs2010 takes +30 seconds to
display the 1st page.
During that time network activity is extreme , the router log shows an
outgoing connection to 207.46.105.140 which is microsoft.
Ctl-F5 has bo delay and no network activity.

The status bar shows loading symbols messages - they appear to be all from
the local hard drive but maybe those are local paths on a remote machine so
I disabled source server support - no joy.

Anyone know what is going on ? And how to stop it - this is annoying to say
the least and a real waste of time.

I'm not sure if this is related to Symbols configuration but you can
easily check it. Go to Tools-Configuration, Show all settings,
Debugging, Symbols and see if you have the Microsoft Symbol Servers
option selected.

thanks Alexey,

that did it - there was a symbol server reference to
http://referencesource.microsoft.com/symbols which nslookup resolves to
207.46.105.140.

I thought that unchecking "Enable source server support" would have disabled
this but I guess I need to look up what the difference is between source &
symbol server - especially since checking "Enable source server support"
give the message "When using Source Server, only use symbol files that are
from a known and trusted location" - sounds like they are the same thing to
me.

....

I just checked my vs2008 config and it is set to use both source server and
the same symbol server - and debugging a web app results in a request to the
same ip but the impact is negligible.
In vs2010 if I check enable source server but disable all symbol servers I
get the same performance as vs2008.

It looks like the 'problem' is the way the vs2008 'Search the above
locations only when symbols are loaded manually" option has been converted
into vs2010. This was unchecked in 2008 and in 2010 was set to
"Automatically load symbols for All modules unless excluded" where imo it
should have been "Automatically load symbols for Only specified modules"
with no modules specified.

All solved.

Glad you got it working.
