I need to transfer 15 files, each is about 1TB sized. >From 9.1-RELEASE[storage1] to 10-RELEASE[storage2] I have tried to run concurrent 'cp' and transfer 4 files at the same time: (executed on storage1) # cp -a file1 /net/storage2/ & # cp -a file2 /net/storage2/ & # cp -a file3 /net/storage2/ & # cp -a file4 /net/storage2/ & But in fact I did not observe bigger throughput Both servers have filesystem exported using NFS, so I can execute copy on source, or destination. Would you recommend running this on source-side, or rather destination-side ? > > Adding the mount option "readahead=8" to the machine receiving the data > might help, if the data transfer command is being done there.

Regarding what I wrote above - how should I mount the NFS volumes?
