Bug ID: 459944
Summary: Choppy performance when resizing window when
~/.config/yakuakerc is on slow media
Classification: Applications
Product: yakuake
Version: 22.08.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: h...@kde.org
Reporter: kugl...@gmail.com
Target Milestone: ---
SUMMARY
Choppy performance when resizing window when ~/.config/yakuakerc is on a slow
media (such as rotational), due to repeated calls to syscall fdatasync. (When
under very slow media, like an old USB drive, the performance is unbearable.)
STEPS TO REPRODUCE
1. Run yakuake with ~/.config/yakuakerc on rotational medium or other slow
medium.
2. Resize the window vertically.
OBSERVED RESULT
While resizing the window vertically, Yakuake process calls fdatasync multiple
times, forcing a physical write to the rotational media, making the resizing
very choppy.
EXPECTED RESULT
At least it should sync only once, using some kind of debouncing. But ideally
not sync at all, since the height of the window is not such an important piece
of configuration.
