Hi.
I've tested IDE HDD performance on 2.5.47-ac6.
Using old pentium-classic PC-9800 box, it has no DMA mode.
1. "hdparm -t /dev/hda3" results (PIO mode)
2.5.47-ac6 with Task file IO: 2.86MB/s
2.5.47-ac6 without Task file IO: 2.90MB/s
2.4.19 without Task file IO: 2.93MB/s
2. Heavy usage test
"cp -pr /usr/src /tmp/foo" (in same HDD)
about 92000files/total size 2.3GB
I had always "lost interrupt" message and FS corruption
by this test at 2.5.20 days.
2.5.47-ac6 works fine. (takes about 30 minutes.)
Thanks,
Osamu Tomita
Osamu,
I know the fix need for taskfile but have not architech the solution in
closed form yet.
