Hello again,
I 'm now using libata on the same system described before (see attached
dmesg.txt). When writing to both disks I think the problem is now worse
(pata_oprof_bad.txt, pata_vmstat_bad.txt), even the oprofile script needed
half an hour to complete! For completion I also attach the same tests when I
write to only one disk (pata_vmstat_1disk.txt, pata_oprof_1disk.txt), whence
everything is normal.
FWIW, libata did not give me any performance benefit, 20MB/s is again the peak
hdparm reports.
Thanks,
Dimitris
