Summary: interupted playback under io load
Platform: SuSE RPMs
AssignedTo: kde-multimedia kde org
ReportedBy: leskets web de
Version: 2.4.0 (using KDE KDE 3.2.0)
Installed from: SuSE RPMs
ARts runs with real time priority. Buffer 0.5 seconds.
linux 2.6.3 with low latency patch using anticipatory IO scheduler
The playback occasionally interrupts under heavy IO load (move of a large directory to a new partition with "nice -n 20"). The IO scheduler does not seem to care much for process priorities (which is good for throughput, but bad for latency).
Maybe Noatun itself should read more data ahead and lock it into memory (if permitted by the OS).
