https://bugzilla.novell.com/show_bug.cgi?id=271069 Summary: improve concurrent disk access Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: bluedzins@wp.pl QAContact: qa@suse.de It is a wish, but I don't know how to set important wish, so I set severity as normal (a bug) because it too often freezes my system. The basic problem is this, that copying, searching large amount of data drastically slows down my computer, but all in all it responds, so it is not _that_ bad. But when two (or more) programs are saving data in the same time, copying, searching, whatever it is not a matter only of poor I/O performance, but the whole system is getting unstable -- I cannot type a command, task-switch takes ages, etc. It this race-conditions does not effect only those apps, but the system as a whole. Please provide some kind of "intelligent" queue which could freeze all the tasks except one in situation when (just an example) N apps tries get a non-stop access to the disk for longer than 10 seconds. Rationale: it is faster to allow app A to copy (or whatever) data, and after A finishes, letting B doing the same, not switching back and forth A and B to access the disk, because access switch for disk takes quite amount of time. Anyway, it is my concern for a looong time :-) but today I lost almost two hours waiting for yast online update and disk scan finishing their jobs being unable to do anything to the system. Two partitions for root and home, Reiserfs, CPU 2GHz. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
