It seems like this should be addressable in the NFS client (or perhaps
even the next layer up). For example, a hypothetical NFS driver that
implements a read-ahead cache, resulting in separate, parallel requests
for chunks of the file.

Given the big price difference between 10G and 1G Ethernet, there's
motivation for a software solution, so I wouldn't be surprised if
someone has created an NFS driver or set of kernel parameters tuned for
these circumstances.
