Bug ID: 505696
Summary: After Inotify got increased its limits 3 times (?),
system is slow and not responsive.
Classification: KDE Neon
Product: neon
Version First unspecified
Reported In:
Platform: Neon
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
SUMMARY
I am using a workstation which had been extremely performant (see SW and HW
below)
and is now extremely slow and not responsive due to letting Inotify increase
its limits.
I installed Kubuntu 26.04.2 just to see it is not my HW but KDE 6.
STEPS TO REPRODUCE
1. KDE neon 6.3.5 - updated
2. having 8 virtual desks and more the 100 konsole windows with login shell
(see screenshot)
3. increase limits as desired by Inotify
OBSERVED RESULT
System is no longer responsive ... games are unplayable ... even TeXLive is
slow.
EXPECTED RESULT
System should be working as fast as before and no more "increase limits" calls
by Inotify would be seen.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon 6.3.5 (24.04.2 based/Noble) - up-to-date
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0
Gears: 25.4.2
Using X11 session (as Wayland has not even session save)
HARDWARE:
Silent Workstation, Zen 4: Ryzen 9 7900, RDNA 3: Radeon RX 7800 XT,
ASUS ROG STRIX X670E‑E, Kingston KSM48E40BD8KM‑32HM 64 GB DDR5‑ECC RAM,
3x Samsung EVOs 870 SATA III 4 TB,
2x Samsung 980 PRO Interne NVMe SSD 2 TB M.2 2280 PCIe 4.0.
ADDITIONAL INFORMATION
I am using 8 virtual desks - each with at least 9 - typically more - konsole
windows
with login shells - a professional workflow.
This might be the cause for the trouble (due to KDE 6 not using resources
efficiently
as KDE 5 did it perfectly) and a screenshot of my desktop is seen here (<4kB
attatchment is a joke):

to give you an impression of the desk and one can see visible problems (two
rectangle showing
background image an not the background of the konsole window) which may be
related to this bug.
As experienced Unix expert I thought a component is dying or a mitigation
hit me ... would have never thought of a system going crazy for monitoting
files.
I just installed Kubuntu 24.04.2 and it works like a charm ... the oposite of
the
dead system KDE 6 created.
Before KDE 6 was introduced, KDE neon was king - nearly perfectly configuered,
fast, reliable - and with KDE 6 I could not even decide which bugs to report
first.
But now this is a game changer - if this is not revoked easily, KDE 6 is dead
for me!
