Hi, since 3 days, my system is pritty slow up to not reacting after a while. Sometimes it is frozen for about some minutes (including Plasma Clock is not running). If I look at the the Plasma Monitor, I see the system is always near 100% (at least some cores). Extract from top, shows that kswapd0 is consuming a lot of ressources, anyhow 32GB RAM should be OK for a simple KDE/Plasma desktop. # top top - 09:17:18 up 1:15, 4 users, load average: 9.77, 8.64, 7.36 Tasks: 397 total, 6 running, 391 sleeping, 0 stopped, 0 zombie %Cpu(s): 11.7 us, 49.2 sy, 5.5 ni, 21.1 id, 12.5 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 31510.43+total, 123.113 free, 7698.504 used, 24290.14+buff/cache MiB Swap: 31502.68+total, 28989.93+free, 2512.750 used. 23811.92+avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 103 root 20 0 0 0 0 R 100.0 0.000 37:10.57 kswapd0 5816 ulf 39 19 0.255t 8.901g 5.012g R 93.75 28.93 55:38.54 baloo_file_extr 111512 root 20 0 0 0 0 R 87.50 0.000 2:06.69 kworker/u32:2+btrfs-qgroup-rescan 598 root 20 0 0 0 0 R 68.75 0.000 30:00.40 btrfs-cleaner 5793 ulf 20 0 3354276 146044 11972 S 37.50 0.453 4:39.36 mysqld 5748 ulf 20 0 3208872 21800 11096 S 31.25 0.068 2:45.96 akonadiserver 6023 ulf 20 0 1428256 50772 40480 S 25.00 0.157 1:57.20 akonadi_imap_re 5078 ulf 20 0 6246912 229212 59300 S 12.50 0.710 7:09.63 plasmashell # top - 09:50:10 up 1:48, 4 users, load average: 11.25, 10.37, 9.74 Tasks: 424 total, 5 running, 419 sleeping, 0 stopped, 0 zombie %Cpu(s): 5.8 us, 48.2 sy, 14.6 ni, 3.6 id, 27.0 wa, 0.0 hi, 0.7 si, 0.0 st MiB Mem : 31510.43+total, 473.695 free, 8782.738 used, 22937.44+buff/cache MiB Swap: 31502.68+total, 28025.43+free, 3477.250 used. 22727.69+avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 103 root 20 0 0 0 0 R 100.0 0.000 68:02.50 kswapd0 4800 ulf 9 -11 566112 11980 7244 R 100.0 0.037 0:38.79 wireplumber 5078 ulf 20 0 6318224 330376 78776 S 100.0 1.024 11:45.49 plasmashell 5816 ulf 39 19 0.255t 7.121g 3.452g R 100.0 23.14 83:20.69 baloo_file_extr 598 root 20 0 0 0 0 R 87.50 0.000 55:32.16 btrfs-cleaner 115138 root 30 10 1015528 582280 4744 D 37.50 1.805 12:03.07 borg 117471 root 20 0 5976 3664 2640 R 12.50 0.011 0:00.02 top # top - 09:56:19 up 1:54, 4 users, load average: 11.27, 11.21, 10.33 Tasks: 411 total, 4 running, 407 sleeping, 0 stopped, 0 zombie %Cpu(s): 8.3 us, 33.3 sy, 5.3 ni, 12.9 id, 38.6 wa, 0.0 hi, 1.5 si, 0.0 st MiB Mem : 31510.43+total, 427.461 free, 8524.664 used, 23192.59+buff/cache MiB Swap: 31502.68+total, 28160.93+free, 3341.750 used. 22985.76+avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4800 ulf 9 -11 566112 10852 6116 R 106.2 0.034 6:46.96 wireplumber 103 root 20 0 0 0 0 R 100.0 0.000 73:09.90 kswapd0 598 root 20 0 0 0 0 R 68.75 0.000 60:20.11 btrfs-cleaner 115138 root 30 10 1015748 920544 6292 D 50.00 2.853 13:31.17 borg 5078 ulf 20 0 6330620 320416 55676 S 12.50 0.993 12:27.42 plasmashell 4750 ulf -2 0 3085516 214216 177584 S 6.250 0.664 19:03.60 kwin_wayland 5816 ulf 39 19 0.255t 7.011g 3.486g D 6.250 22.78 87:57.58 baloo_file_extr After killing wireplumber and baloo_file_extr, as well swapoff -a # top - 11:07:16 up 3:05, 5 users, load average: 7.87, 6.71, 6.60 Tasks: 404 total, 3 running, 401 sleeping, 0 stopped, 0 zombie %Cpu(s): 10.4 us, 29.6 sy, 0.0 ni, 41.5 id, 16.3 wa, 0.0 hi, 2.2 si, 0.0 st MiB Mem : 31510.43+total, 310.660 free, 6013.328 used, 25934.19+buff/cache MiB Swap: 0.000 total, 0.000 free, 0.000 used. 25497.10+avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 103 root 20 0 0 0 0 R 100.0 0.000 136:32.70 kswapd0 598 root 20 0 0 0 0 R 87.50 0.000 117:38.18 btrfs-cleaner 5793 ulf 20 0 3354276 215228 8964 S 50.00 0.667 16:26.30 mysqld 5748 ulf 20 0 3208872 27960 10324 S 31.25 0.087 7:57.38 akonadiserver 6023 ulf 20 0 1428256 41056 14760 S 25.00 0.127 5:34.51 akonadi_imap_re 7598 ulf 20 0 2302032 197316 156856 S 6.250 0.612 12:04.02 konsole

Seams that it was the reason, I have no issue anymore. CPU load is mean 50% lower (with low CPU clockspeed in the range of 5%). If I look in the system settings, the Index memory is about 811,7 MiB, which is according the scanned about 250GB local and NFS mounted quite small. I disabled the scan of an NFS drive with about 11TB anyhow, due to performance reasons. Do you or someone else know, if there is a log I can check which file seams to be the reason? Ulf

No, I don't know. Years ago I had problems with baloo, and there were messages in the system log about crashes with this file or that. But There were crashes, it is not your case. Found something: https://community.kde.org/Baloo/Debugging «You can check which files are currently being scanned with balooctl monitor and the current indexing status with balooctl status.» -- Cheers / Saludos, Carlos E.

New seams to be balooctl6 But to start debugging I need to start it again. But now I will went to Holidays and don't do PC stuff the next 2 weeks. Ulf

Hi,
since 3 days, my system is pritty slow up to not reacting after a while. Sometimes it is frozen for about some minutes (including Plasma Clock is not running).
If I look at the the Plasma Monitor, I see the system is always near 100% (at least some cores).
