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:
NFS timeout
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''.
See also ``Everything works slowly'' for information on other performance-related issues.
