That's pretty much what you would expect. The trace shows
that your program reads sequentially in 61k chunks. Given
that your network latency is roughly 600 microseconds,
ftp://pserver.samba.org/pub/unpacked/junkcode/expected_throughput.pl
gives 55MB/sec. You might want to try smbclient, that does
larger parallel reads, or a copy program that uses multiple
threads simultaneously.
