[Gnewsense-dev] usb disk speed improvement

[Giuseppe Sacco]

Hi all,
I am using an external usb disk PATA on a fuloong mini 2e. It works, but
it works really slow as shown by hdparm:

sh-3.2$ sudo hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   282 MB in  2.00 seconds = 140.90 MB/sec
 Timing buffered disk reads:   32 MB in  3.02 seconds =  10.59 MB/sec
sh-3.2$ sudo hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   168 MB in  2.01 seconds =  83.60 MB/sec
 Timing buffered disk reads:   42 MB in  3.14 seconds =  13.37 MB/sec
sh-3.2$ sudo hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   282 MB in  2.01 seconds = 140.18 MB/sec
 Timing buffered disk reads:   42 MB in  3.10 seconds =  13.55 MB/sec

(Same disk, same kernel version, i386 architecture, give about 40Mb/sec)

Is there any kernel parameter or other setting I could change in order
to have a better I/O performance on the fuloong?

Thanks,
Giuseppe
