Slow speed of USB flash disk on Dell E6320 with current

Tomas Bodzar-4
Hi all,

I'm getting slow speed with USB flash disk mentioned below. It's on
new laptop, but same issue was on previous Dell workstation. It's
running mostly around 6MB/s or less regarding info from systat. In
this case xfe (see top -CST -s 10 output) was used, but it's same
either in console or X. On Linux/Windows  it's running around 20MB/s
during copy/write of same files. Unplug is possible to do immediately
so probably not so much cache in use on those systems (didn't not
check deeply in fact).

Is there something what can I try/check/modify to see better speed?

Thanks a lot

I have generally noticed that reading/writing to usb flash or hard
drives is slower using openbsd compared to linux. I believe it has to
do with usb2.0 not being fully implemented.

You will get better speeds on openbsd depending on which filesystem you
use. For example, copying speeds will be faster if you format your
flash disk to FFS instead of msdos (not sure if you did this already, I
could not see disk format in the outputs from your email).
