It's times like this that make paying off student loans suck, get paid well, but someone else gets the pay check :/. How well is the Eeebox working over all? I have been thinking about something like that when/if can actually spring for real den system. Evam -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

You could try getting less days of data for your TV.xml to see if a smaller file makes a difference. How many channels do you have? I have 19 channels. I normally grab 10 days worth of data with tv_grab_uk_rt and then run tv_sort on it. I've just changed this to 1 and I'll do a test with that tonight and report back. With a small TV.xml (77K) and scrolling programs the load on the P3 is about 12% but it is difficult to say. I know some of the P3s I've encountered make much more modern chips look poor. Mostly thanks to a 512kb L1 cache. Could you be a bit more specific about what slow is? I did do some timings on the TV guide once upon a time. The timings were about 0.5 seconds when scrolling about on a 733MHz P3. Duncan Once I scroll off the data (or page if that's a better way to describe it) that's displayed initially there's a long pause. I have too many channels to list on screen at one time so for this to happen I can scroll down until the guide has to start loading the channels that weren't being displayed or alternatively scroll right or left to times that weren't displayed. Once I do this I hit 100% cpu usage and the guide pauses for maybe 250-500ms per half hour or hour of the guide that's updated. Obviously this makes scrolling extremely slow, the lirc commands will actually get queued as it's not refreshing quickly enough meaning it's impossible to tell where you might end up from holding down the remote for a few seconds. A quick test with no TV.xml shows when I down scroll through the empty guide to the channels that aren't displayed originally shows no delay at all when the screen has to draw the next channels. CPU usage shows 60% to 75% though while doing this. With POLL_TIME=0.05 freevo's CPU usage is at ~19% when idle.

Scrolling still suffers from the same pauses. The delays are longer than I'd reported. It's ~1000ms to 1500ms to change to a channel that wasn't displayed or move forward or back in time. It's ~100ms to change between entries on the page that are already displayed. The CPU usage is around 80% when changing between items already displayed and goes to 100% when it has to show new data. I can't believe that a P4 2.4GHz celeron could be this poor. Could there be another explanation? I've checked cpufreq-info and it's running at the full clock speed.

Does anyone using freevo-1.x have a guide that's nice and responsive to scroll through? If so can you share some details of versions, processors, cpu load, etc. that might shed some light? Thanks, John Both running 1.8.3 1. Intel Quad Core model name : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz stepping : 11 cpu MHz : 1596.000 cache size : 4096 KB Scrolls well doesn't choke on the job One core will get to 50%, no more TV.xml 1.5M 2. Intel Dual Core model name : Intel(R) Atom(TM) CPU N270 @ 1.60GHz stepping : 2 cpu MHz : 1607.996 cache size : 512 KB Definitely slower, but still very usable One core gets to 100% TV.xml 1.8M Gees' wish I hardware that nice for freevo, or my desktop for that matter. Anyway my guide fine on my freevo system. I don't use it much becuase watching TV is just easier using the TV due to other issues with playback. I am using 1.8.3 on a 3ghz Celeron with a gig of Ram. TV.xml is about 8.9 meg. Evan -- ___ Freevo-users mailing list Freevo-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freevo-users
