What "medication" are you on?

But, just as an aside of course, which Olympic standard accepted timing
device are you using to come up with this timing difference?

"0.05s", eh?

Gosh. Oh gee.

Tsk.... "0.05s"....Tsk...what a waste of time when using Maverick....Oh
gosh.....

I could comment on this but I claim not to do so under the 34th

Open up another terminal and run 'top'; check to see if you are getting
high cpu usage. Do you by chance have an nVidia card? If so, these might
be worth a read:

<https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-180/+bug/617994>
<https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/629910>
Seems there are some font rendering issues.

You can also try GtkPerf (sudo apt-get install gtkperf) to test:
http://gtkperf.sourceforge.net/
http://packages.ubuntu.com/en/maverick/gtkperf

Even in lucid, on this system:
Without LCD subpixel rendering:
Total time: 17.20
With LCD subpixel rendering turned on:
Total time: 25.57

In any event, it may be a combination of things; cpu usage, graphics
rendering, USB subsystem if a USB keyboard, etc., etc. Your best bet is
to check launchpad to see if you can find a similar issue - or file a
bug report so the problem can be fixed before release:

Best advice he could get. On the initial startup of a newly installed
system there are several culprits running that eat the CPU at first.
Just a plain updatedb, at the wrong time, will do that. If the OP spots
what is eating cpu and/or memory using top, he'll spot the problem right
off, most likely. Ric

htop has the disadvantage of when you press quit (q) the data disappears
from the terminal. Hence you can't do a cut & paste to this for
troubleshooting etc. top on the other hand allows me to do this (I've
not reformated for email as I'm too lazy to do so now):

Try that with htop & let me know how you go.

Thanks for your help , you're exactly right
I'm using a nv video card and it's the font rendering problem

Maybe it will be fixed soon

Thanks for your help , big thank you

True. They both have their uses. I usually just want a quick visual
'snoop' with no copy.
