Public bug reported:
I always wondered why audacious was using such an insane amount of CPU;
nearly 20% of my CPU on my laptop, while reading nothing, even when
being hidden. In the end I started to strace the process, to see wtf it
was doing:
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN},
{fd=8, events=POLLIN}], 4, 29) = 0
gettimeofday({1215268505, 913189}, NULL) = 0
read(3, 0x81350d4, 4096) = -1 EAGAIN (Resource temporarily
unavailable)
gettimeofday({1215268505, 913274}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN},
{fd=8, events=POLLIN}], 4, 29) = 0
gettimeofday({1215268505, 945156}, NULL) = 0
read(3, 0x81350d4, 4096) = -1 EAGAIN (Resource temporarily
unavailable)
gettimeofday({1215268505, 945250}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN},
{fd=8, events=POLLIN}], 4, 29) = 0
gettimeofday({1215268505, 977160}, NULL) = 0
read(3, 0x81350d4, 4096) = -1 EAGAIN (Resource temporarily
unavailable)
The funny bit is, these stopped when I disabled "Autoscroll songname", and the
CPU usage dropped to what I would expect it to be.
In other words: the "Autoscroll songname" thing uses up to 20% of the CPU of my
laptop, even when the window is hidden. Quite a CPU-expensive way of reading
music :( With it disabled, it's fine.
