so, the problem with this entire conversation is that none of you are actually 
measuring anything. while i'm sure it's enjoyable to gripe about things, 
without measurement there is no way to know:

* where in the code the problem(s) actually lie

* what the cause of the problem(s) are

* the severity and type of the problem(s)

without that information it's quite impossible to make things better. if you 
want to help improve things, then investigate and measure. do some sleuth 
work. simply saying "oh, we should have a version that does $FOO" will likely 
end up with little improvement and just as likely provide a worse experience.

someone mentioned kio slaves, and that's an interesting case in point. "plasma 
was really slow" was the report we got from some people; turns out it was 
kio_http that was going nuts and taking 100% cpu. it was getting launched by a 
plasma widget that uses http, so it gave the impression it was plasma. in that 
case, it wasn't.

there are other such examples. so while there is certainly room for 
improvements, there's work to be done to make them happen. leaping to 
conclusions without doing the investigation part of that work doesn't help, 
but just spreads misinformation which some of us then get to spend the next 
years cleaning up after.

i want kde4 to be as fast as possible, just like you. let's try and actually 
make that happen.
