If a networking adapter is not fast enough to keep up with the data it is
asked to transfer, NFS can experience delays, timeouts, and error
messages when engaged in large data transfers. If this happens
with NFS, you see this error message:
To work around this problem, specify a smaller read-and-write buffer size in your NFS mount options. 1024 is a reasonable value for slower adapters. For more information about configuring this option, see Read/write buffer size in ``NFS filesystem advanced mount options''.
