[Pvfs2-users] I'm in the dark, need someone to shed some light

[Phil Carns]

Hi,

Which part is unexpected?  If it is the cp time, then you might want to 
try the experiment listed in this email (though you can reverse them to 
go from pvfs2 to local disk if you are interested in read performance):

The cp utility might be picking a poor access size for PVFS depending on 
your version of coreutils.

How fast is your network and how big is dvd.iso?
