I did the tail the verbose log from a laptop over ssh thingy and found the
following.
It takes a second or so for the mysql SELECT to come up on the screen. Then
it takes between a second or so for the screen to change. If I move down
channels each second or so with the remote I can get ahead of the display by
5 or so channels.
SELECT data FROM settings WHERE value = 'ChannelFormat' AND hostname =
'mythfrontend' ;
2007-06-20 20:53:36.299 MSqlQuery: SELECT data FROM settings WHERE value =
'LongChannelFormat' AND hostname = 'mythfrontend' ;
2007-06-20 20:53:36.305 MSqlQuery: SELECT icon FROM channel WHERE chanid =
'1020' ;
2007-06-20 20:54:24.246 MSqlQuery: SELECT icon FROM channel WHERE chanid =
'1013' ;
2007-06-20 20:54:27.040 MSqlQuery: SELECT icon FROM channel WHERE chanid =
'1077' ;
2007-06-20 20:54:28.745 MSqlQuery: SELECT icon FROM channel WHERE chanid =
'1056' ;
Top shows me using up pretty much all of cpu while changing through
channels.
My memory is all gone but I'm not into the swap yet.

Now look at my cpu and X when I'm moving through the menu's outside of
"Watch Recordings" And this is smoothly going through the menu's at a couple
a second.

Now I'm thinking some sort of GL thing? I see the GL fades and whatnot on
the main menu's so I know it's working. Hrmmmmm.???
