KDE4 isn't<br> as snappy as KDE3 to the end user. It's not just people's \
imagination.<br> Another one i noticed today was just clicking on the system tray \
icon<br> for amarok. KDE 3 ( my workstation at work) appears instantly, where<br>
as my much more powerful KDE4 home computer still takes a few moments<br>
for it to appear. (also not running oxygen)</blockquote><div><br>hmm... amarok \
appears instantly for me. I am using Oxygen. I do have all of the composite stuff \
turned on though, so it might be caching the window when it hides \
it.<br>&nbsp;</div><blockquote class="gmail_quote" style="border-left: 1px solid \

all get better eventually. KDE3 certainly got faster<br> every release. It's just \
that for some people, at the moment, no<br> matter how 'complete' kde4 is , it might \
not be fast enough on their<br> setup for what they do. Kdevelop on kde4 is quicker \
for me than kde3<br> so for what i do, KDE4 is more appropriate but everyones use \
case is<br> different.<br>

so good, it feels like I'm looking for things to complain about.<br><br>On my laptop, \
things are a bit worse. What bothers me most is that window management isn't as \
perfect or snappy as it should be (particularly with gtk apps). Most of this probably \
isn't kde's fault so much as simply not having an accelerated graphics card though \
(though Windows XP seems to do well with integrated \
graphics).<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid \

&gt;&gt; i think that's rather the autocompleter - but nothing i could reproduce<br>
&gt;&gt; here (other than krunner has always been a little slower...)<br>
&gt;<br>
&gt; I certainly see this pause from time to time, but it's not consistent, so it<br>
&gt; probably would be difficult to track down.<br>

have kmail configured, so it probably wouldn't be reading anything), and didnt' get \
any input latency. Some things which did cause latency for me:<br><ul><li>the first \
time the klipper history is brought up (all the time)</li><li>browing a large folder \
previously uncached, e.g. /usr/bin locks up dolphin</li></ul>more readahead might \
also help (e.g. in gwenview, scrolling the thumbnail bar isn't perfect; though the UI \
doesn't lag, it takes a few seconds for the thumbnails to get filled \
in).<br><br>regards,<br>Nicholas<br>
