First, for only four workstations, you should be on a Peer to peer
network without a server. However, since you are using one, the file
server is the single most important part.
Rule 1. Never skimp when it comes to the file server. Don't use cheep
        parts just to save a buck, or some work. If this crashes, your
        whole network is useless. None of that Cyrux or AMD processors,
        or DTK motherboards or cheep Packard Hell systems...
Rule 2. Memory is power. You should never, and I repeat NEVER have less
        than 16 Megs of memory in a file server. The server uses the
        memory for quick access, it's own management, and a large
        variety of other things. You can double the performance of a
        network by simply increasing memory. When doing so, remember
        rule number 1.
Rule 3. It is only as fast as it's slowest part. The hard drives,
        processor, memory, controllers, NICs, and Workstations all
        contribute to the speed of the network. The processor determins
        the speed of which information is processed. But, the real
        factor is how fast it is passed. The 10Base-T/2 NIC is probably
        the fastest part of the network. Transmitting 10 Million bits of
        information per second. The hard drives almost never go that
        fast unless you are using a SCSI2 drive. The controller card
        makes a big difference also. Use either a PCI, EISA, or VESA bus
        NIC and Controller in the server. It's parts are trying to send
        to every other computer on the network so they have to be fast.
        This is one reason why memory is so important.
My file server serves 150 nodes on a Wide Area Network (WAN) and the
utilization usually stays around 5 to 10 percent. Why? Because I have
fast SCSI hard drives, a EISA NIC card and 72 Megs of RAM. It runs quite
well.
