We got a couple of independent threads going on here; so, it looked like a
better idea to start another than to get buried in either.

First question is one of architecture. Second is of capacity.

Is this installation stricly Client/Server (2-tier) or are most of the
requests being fed through an application or middle-ware server (n-tier)?

If this is most likely a client [that is a workstation(s)], then looking at
upgrading all of the client NICs, memory, cpu, and/or OS might be cost
prohibitive. A look at an n-tier design might yield better performance
increase due to distribution efficiencies.

If this is already an n-tier architecture, then it is probably a cpu and/or
memory issue on the application/web/middle-ware server, or all three,
perhaps. Check out the Bytes and Packets Sent/second statistics in
Performance Monitor on all hosts in the system. The one with the lowest
throughput in the chain is probably your bottleneck.

Sincerely,

Anthony Thomas

My waitstats reveal a high percentage of networkIO. Currently my adapter is
a 100Mbps. Do I need a 1Gbps adapter ? How can I find out why theres a high
wait of networkIO and what can I do to resolve it ?
Thanks
