I'm having problems w/ client latency when ever I have more then 8 clients on my server. I have checked bandwith & cpu use when I've had 10 clients. W/ 10 clients I had <30% CPU utilization & <15% bandwitch (bytes sent & recieved). My server is running on dual celeron 563 MHz (OCed) & 10Mb connetion. OS is XP Pro, which I believe the max client connections is 8 for XP. I'm considering rebuilding server w/ W2K, but would like some thoughts 1st.
