I'm trying to share the DVD over NFS.
I have updated /etc/rmmount.conf with the following line:
share cdrom* -o ro,anon=0
Everything works well, except the reading speed, which is quite slow.
Copying a ~200MB file from DVD over NFS takes ~12 minutes.
Copying the same file from DVD to the local filesystem takes ~2 minutes,
and copying this file from the hard drive over NFS takes ~20 seconds.
This makes me believe that the issue is in the interworking of the NFS and DVD-ROM, for (hypothetical) example,
the disk can not spin up to the max speed due to the random access.
Has anyone tried sharing the DVDs with good performance? Should I read up and tweak some NFS parameters or abandon the idea of achieving good performance?
I'm using Solaris 10 Update 7.
Thanks in advance for any suggestions.
Thanks for the suggestion.
I'm not sure if it's applicable for my issue. From what I've read, it may help if the same data is read over and over,
but not with the reading speed of just inserted DVD disks which are not yet cached (which is the usage pattern I'm trying to optimize for).
