Capacity planning for Windows

[David Garcia]

Greetings,

We’re currently live on a 5.3 Windows 2000 system with about 25 live interfaces. Message traffic is somewhere between 45-50K messages a day. Over the next few months we will be adding about 20 new interfaces and the message volume could reach 100K messages or more.

At what point does Windows hit the ceiling as far as the number of interfaces or messages? I’ve heard that 50 interfaces or 100K messages is the practical limit. Anyone running more than that on Windows?

Any comments would be most appreciated.

Thanks!

David

We are on W2K and have 57 threads with 259 interfaces.  Our peak message flow is 198,000 per day.  We have not seen any degradation in latency.

Our server has quad 1.5 gig processors and 4gb memory; development and production are separate servers.  We’re going to add a second production server first quarter next year because we will be almost doubling our thread/message count, and didn’t want to take any chances.
