[mythtv-users] Is the GUI slow for everyone or just for me?

I don't know if I can help...  can you benchmark and compare it to something ?  
By doing a kernelcompile maybe ?  Does bonnie++ uncover any obvious weak 
spots ?  Have you overclocked it ?  What does acpi report back as system / 
CPU temperatures ?

You may also want to verify in your BIOS that CPU internal caches are ON.
And of course, the obvious -but you checked that I hope- hdparm DMA mode.

For more technically inclined people, it may be insightful to run iostat or 
other tools from the sysstat suite to see where exactly the bottleneck is.

Failing all that, if you remind me in a couple weeks (too busy now) we can 
directly compare my system to yours. Mine is an athlon 2600+, VIA KT600, 
256MB, kernel 2.4 running Myth 0.14, so it is more or less comparable to 
yours (except RAM). It has no slowness and encodes straight to mpeg4 with 
many CPU cycles to spare (resolution 480x480 @ bitrate 3000).
The menus feel 'reasonably' snappy, both on remote- and local frontends.
(2-4 second wait to open "Watch Recorded Shows" with over 100 shows listed)
