That is on Qt4.4.0? And on Qt4.3. ? I know you have to downgrade to 
test, but if you backup your current pkgs its easy to restore.

Hm, how do you explain the results I get? No matter whether KPorts needs 
240k connections, a slow-down of multiple minutes vs seconds just 
depending on the qt-version is definitely a bug in Qt.

JuK takes 5minutes to start (5 Minutes to actually show the main 
window!), on a CoreDuo at 1.66Ghz. That isnt right! 
Opening a Directory or Webpage in Konqueror also has slowdown that could 
be related to memory allocation and connection-creation, since I guess 
konqueror does a lot of that when loading a web-page...
