I have about 200 web feeds in Thunderbird 3, everytime I click on the "check new items" icon for them or when Thunderbird checks them periodically, I get an intensive hard drive usage during several minutes often leading to Thunderbird becoming unresponsive until the task is finnished.
Myk, David any logs would help you diagnose what the issue might be ?

Pascal, do you still see this with version 3.1?

This is presumably because Thunderbird kicks off 200 simultaneous network requests when you "check news items".  The fix would be for Thunderbird to limit the number of simultaneous network requests it makes for feed updates, issuing, say four to five initially and then a new one every time a pending one completes.
It doesn't help that these network requests run on the ui thread either.
