Bug ID: 482167
Summary: Default refresh interval is too fast
Classification: Applications
Product: plasma-systemmonitor
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: herzensch...@gmail.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
I'd like a more reasonable refresh interval for plasma-systemmonitor. Currently
it updates at about half a second or less. Or as the "Minimum time between
updates" setting says: "No limit".
Fast graphical refresh intervals are a well known way to get an application to
use too much CPU, and this issue becomes even worse in conjunction with
https://bugs.kde.org/show_bug.cgi?id=429152 (Graphs can consume excessive CPU
resources on platforms with weak Intel GPUs and high-resolution displays).
A system monitor should be lightweight and quick to process, and thus reliable
when the machine is under stress, it shouldn't be using as many hardware
resources as it does.
The default should be something more reasonable, probably something between the
range of 1s to 2s.
1.5s is probably the best compromise.
