I find using iperf is very useful as a first "port of call" in this sort of situation. It is a client/server network tool. One can (for instance) run the server on the destination and then run a network test -- optionally bidirectionally -- from the client. This will give you an excellent idea of what your maximum network bandwidth might be. Taking off tcp/ip overhead a 100Mb/s network is unlikely to see more than about 95Mb/s (bits/sec) or just under 8MB/s (bytes/sec). I guess a gigabit network might do 10 times that. If iperf doesn't provide the answers (or clear area of problem-finding) for you, you should move down to the disk level. Watching iostat or iotop might be a good place to start. -- Rory Campbell-Lange r...@campbell-lange.net ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
