I have a small network in an office. A Debian server supplying /home
directories to a small group of Ubuntu clients using NFS4. Typically
there will be about 1/2 dozen people using the network, authentication
is via NIS and the server also acts as a gateway to the wider world.
Networking is 100Mb ethernet distributed around the office by a couple
of switches.
This all works fine and is generally quite responsive but occasionally
it seems to go into super-slow mode. For example: yesterday someone
tried to open a large (24mb) pdf on the network and it took several
minutes to open.
I have checked routing tables, DNS and mounting NFS shares async.
Any thoughts on why this might occasionally happen - seems a bit random.
