Package: htop
Version: 1.0.1-1
Severity: normal
I am debugging a CPU usage problem with my audio player, Amarok. My PC
has an Intel Core i3, which has 2 CPU cores and HyperThreading. Debian
considers this as 4 CPU-s. Amarok is using between 0 and 3% of a core
when it's idle. Since this is small, I need some precision to measure
the problem and to tell its severity.
I used top, but top is not too accurate itself. With a 3 seconds delay,
it reports CPU% as fractions of 300. in my case, that means it usually
shows either 0.3, 0.7 or 1.0 (at this time, Amarok is averaging about
0.7%). So I tried htop to see if it would provide more accurate
readings. It turns out htop displays worst values.
If using -d 10 (one second updates), htop usually displays CPU% as 0.0,
and only quite rarely 1.0. Meanwhile, TIME+, which displays as x:yy.zz
(minutes:seconds.hundredths of a second), grows at most updates, meaning
Amarok usually takes more than half of a hundredth of a second of a
("virtual") CPU's time per second.
htop never displays a digit other than 0 after the decimal point. Even
if I use -d 100, htop shows Amarok as using 0.0%.
Ideally, htop should display only significant digits (by default, at
least), and should round up past 0.5. Addressing one of these issues
would be a good start.
