Server requirement for Ajax Comet

Hi there,

Anyone here has experience in Ajax Comet? If I'm gonna setup a system for live streaming using ajax comet technology. The number of users concurrently using the system will be around 200-300 users, and the amount of data pushed from server to client is a string with maximum 50 chars length.

Could anyone let me know what kind of server architecture is required? How many servers are needed to drive the system?

Your inputs are very much appreciated.

This will depend on the frequency of chatter between each of the possible 300 clients and the server. Are you saying 50 characters every 5 seconds? 10 seconds? How often?

Say you are using all 300 users transfering 50 characters. That equals roughly 15,000 bytes. So now we arrive back at the how often question. That will determine the server requirements.

Hope that helps some.
