Hi, My problem is: when I'm watching a video, running Konversation in the background with logging on disk enabled, the playback of video slows down, freezes for a while. Running iotop and ksysguard I found that baloo_file_extractor is writing on disk a big amount of data, filling the write queue; balooct monitor shows baloo is indexing Konversation's logs file changes. Peaks of 60-90 MB/s of data on mechanical hdd are generated and the playback of videos (or audio, or other GUI-related tasks) slow down or freeze. Very very annoying. I'm running updated versions of: KDE plasma (5.12.5), kernel (4.16.7), baloo (5.45); CFQ I/O scheduler on sda. On the same machine, the same version of softwares, the same configurations (of programs, mounts, IO scheduler) BUT on a Debian sid install (home is shared between installs) is NOT showing the same issue. On Debian, playback is running smootly even if baloo_file_extractor is heavly loading IO writes queue. On each installation I added this tweaks, to improve Vm management by the kernel: [frapox@tungsteno ~]$ cat /etc/sysctl.d/local.conf vm.dirty_background_ratio = 2 vm.dirty_ratio = 5 vm.vfs_cache_pressure = 60 I also tried to recompile the Arch kernel with CONFIG_PREEMPT_VOLUNTARY=y, to reflect the same default compile setting of Debian, but the issue wasn't solved. So i'm wondering which other config files or settings/tweaks I can look into to overcome this issue on Arch linux (I'd really love to keep on use Arch as my main OS). Thanks in advance. -- fp
