Thanks for the suggestions guys This system is fine up to about 8 clients.
hdparm gives this with 6 clients happily using open office and firefox. They are saving files onto a separate server via NFS. Timing buffer-cache reads: 852 MB in 2.01 seconds = 423.31 MB/sec Timing buffered disk reads: 90 MB in 3.02 seconds = 29.76 MB/sec Then this is with 15 clients during a period of unacceptable delay: Timing buffer-cache reads: 376 MB in 2.96 seconds = 127.13 MB/sec Timing buffered disk reads: 94 MB in 3.01 seconds = 31.20 MB/sec Are these figures bad? They look ok compared to some I found on the web. yes I have DDR RAM I will find a P4 that fits and see how that goes. It would be great if more people could chip in with their examples of what works for 20-25 clients. I don;t get how to have a server just for open office. How do you do that?
