Konqueror 4.1.3 times out all the time


On SuSE 9.3, I preferred Konqueror over Firefox because it was so much faster. Now, with SuSE 11.1 and Konqueror 4.1.3, it is not only slower, it also times out very often. Whenever I start it, it doesn’t display my home page but tells me it’s not accessible. It displays it just fine after I press the ‘Reload’ button. Same with logging in to this forum.
I disabled beagle. What else can I do to make Konqueror more responsive?

Shoot… when I hit the Submit button, I get again “The requested host could not be found”.
If you see this, it worked the second time.

Thanks, Stephan
