Let me just share my case. I'm on AMD64 (and therefor I am supposed to accept programs swallowing huge amounts of memory).
Now, this is the line from 'top', it's the third biggest memory hog on my machine (running Gnome, Fx3, OOo, Icedove etc): 9154 gustaf 20 0 551m 182m 13m S 0 4.6 2:52.34 /usr/lib/ontv/o So out of 551 megs (which forces other apps to swap and make the system lazy and require a dozen seconds delay to responds to virtual desktop switching after a few hours of non-usage), 182 megs are directly being used for OnTV. This is outrageous. And just the fact that ontv has actually allocated _half a gigabyte_ is absolutely I-don't-know-what... WTF?! Just some quick math: Let's say I care about (have registered for) 10 channels. They have 50 programs per day, and I have a few days (say 3) in beforehand. This means 10 x 50 x 3 = 1500 tv programs. Let's say they have in general, about 500 bytes of info (title + description, and this is probably far over reality). This would mean .75 megs. Let me repeat myself, ontv eats 182 megs. Ok, there are some channel logos and some libraries, but come on! The fact that OnTV stores _everything_ isn't a good enough explanation to why it has to just swallow such huge amounts of ram. The lunatics doesn't end here; When I haven't right-clicked the OnTV applet icon for a while, doing so causes the system to completely freeze for several seconds (I see lots of CPU usage on my load applet). This program really acts like some enterprise data center super program, when in fact all it does is present a little TV info. My suggestion: When reading new shows (updating), convert the data into an SQLite database. Each minute, read the current (and +1) shows so that the GUI can quickly show it. Searching and other operations can easily be converted into SQLite queries. In other words, almost no programs will be resident (or even allocated) in memory. This should drastically lower (if not minimize) the memory usage, and if this isn't enough, then perhaps someone will be kind enough to move this from python into something less memory hogging. It's a shame that such a good little app is one of the worst hoggers on the desktop. -- Ontv uses lots of CPU and memory when updating tv listings https://bugs.launchpad.net/bugs/191700 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
