Why is tar so slow at writing to a cifs share?
This is on Ubuntu 10.04.
I can write to my cifs share at 250 mbps with cp.
I can tar over my nfs network at close to gigabit speed.
But when I tar to my cifs share, I am only getting 70 mbps.
Any idea how this can happen?
Here is my mount command from /etc/fstab:
//zzz-address /zzz-mount-location cifs credentials=/root/smb/credentials.mbb,uid=0,gid=0 0 0
And here is the tar command:
tar --listed-incremental zzz.snar -cpPf zzz.tar
Any help would be greatly appreciated! Thanks.
