Has anyone else noticed logging on to KDE under F-12 to be slower than
on F-10/11? Are there any tools out there to record timings of the
login process to see what might be taking longer?

Indeed I have noticed -- the login seems to have a long pause at
whatever stage 2 dots on the splash screen refers to. (Observed on both
a 64-bit Core 2 Duo and a 32-bit Pentium III machine.) If someone has a
machine running kernel 2.6.32 around (i.e. rawhide), a "perf timechart"
of the login process might be very interesting...

Yup, second dot takes the longest.
I have a rawhide laptop at home that I can try "perf timechart" on.

I think we'll need some more logging from within KDE. I modified
bootchartd to stop after I logged in and I can see various processes
start but really no idea what is being waited on.

Stages are defined here

But I'm not sure how to read this.

My pauses seem to be at 1 dot (waiting for kded?) and 5 dots (waiting
for "ready").

5 dot issue may be:

fixed in 4.3.4.

Are people still seeing slow logins? My system does indeed seem to be
much better after upgrading to 4.3.4.
