Hello misc,
it's about some time now that I use an external USB drive as my
primary boot drive with OpenBSD, but I'm not satisfied with the
performances as I couldn't get over 10-12MB/s.
I don't think this to be a problem with the hardware as I have the
same issue with different pc/drives as well as better performance with
different OS.
I searched through the man pages as well as the mail archives and the
internet, but couldn't find any clues explaining me if I'm doing
something wrong.
Any ideas?
Thank you.
Ciao,
D.
ps. Here are the two systems' dmesgs, updated a few hours before build time.
