I'm right now testing Con Kolivas' patches in my workstation, and it seems
great. I still want to try WOLK in our servers.
However, after having compiled CK's patch with all my usual options
(activating only support for my motherboard's chipset, etc.), I find an
annoying thing:
adelita:~# dmesg|grep ST380
hde: ST380023A, ATA DISK drive
hdg: ST380021A, ATA DISK drive
adelita:~# hdparm -d1 /dev/hde /dev/hdg
/dev/hde:
setting using_dma to 1 (on)
using_dma = 1 (on)
/dev/hdg:
setting using_dma to 1 (on)
using_dma = 1 (on)
adelita:~# hdparm -t /dev/hde
/dev/hde:
Timing buffered disk reads: 64 MB in 2.75 seconds = 23.32 MB/sec
adelita:~# hdparm -t /dev/hdg
/dev/hdg:
Timing buffered disk reads: 64 MB in 2.04 seconds = 31.37 MB/sec
Both disks are almost identical, the only different is that hde (which btw is
my / disk) has hdf as slave in the same bus. They always had similar
throughputs, but hde's seems to have lowered with this kernel patch and I
cannot get to imagine why.
Anyway I'll keep on testing it. Performance in my workstation seems to be a
little better, now I'll put hands to work to compile WOLK in the servers :-)
