Maximum blaze users for my app?

Question

What exactly does it mean when adobe says Blaze will support "hundreds of clients per CPU"? I am thinking about using Blaze with polling. Does this mean that only a few hundred clients can use the app at once? We would have at minimum 5,000 clients using the app at once....as long as only a few hundred of that 5,000 are polling at once I should be fine, right? no?

Answer 1

You are thinking in the right direction. I am tempted to say, sure, your application can support 5000 concurrent users, but every application is different - recommend performance testing to be sure.
BlazeDS has no secret lock to reduce the number of users it can handle - it's purely based on the hardware limiations and software configurations. There are some fundamental differences between BlazeDS and LiveCyle Data Services (LCDS) you should be aware of:
1. All connection between BlazeDS and the Flex client is through a Servlet, and is usally a blocking connection. This should not be a problem if you use polling. LCDS on the otherhand support an NIO (based on Java new IO API's) server. NIO connections are non blocking - they only block a thread when the client making the connection is active. This difference is important when you use streaming (server push) than polling.
2. In addition, only LCDS supports RTMP (Real Time Messaging Protocol). You should look up to understand this protocol to determine if this is relevant for your application
Hope this answers your question.
