[bt-devel] BibleTime 2.0 released

[Martin Gruner]

Hi Joachim,

opening a main window menu is a Qt operation. So my guess is that the 
performance problem might be inside Qt itself? It is hard to explain why other 
apps should run fast, though....

I just checked yesterday: if you install kcachegrind and valgrind, you can run 
"valgrind --tool=cachegrind ./bibletime" to profile BT. The resulting file can 
be opened in KCachegrind to see where most performance is lost. It would be 
very helpful if you could do that.

Maybe we messed up some event handling code in Qt.
