BlazeDS default messaging for 1500 clients

Question

I am having Flex + Spring BlazeDS Integration + Java combination for my project. This project is deployed on weblogic server. As we know whenever a client connects to blazeDS it blocks one thread on the server and it is a limitation for the maximum number of concurrent clients for one BlazeDS instance.

In my case I am supposed to have around 300,000 updates every hour and at any moment of time around 500 concurrent client can be there. In extreme case it can be all 1500 clients connected to the application. What is the best possible solution for that?

If I try to convince my clients to use LCDS they would like to know the exact number that our current setup can support. For that I tried to use neoload but could not make much progress in that direction.

So If any body has used such a setup and can advise me what shall I do, it would be really great!!

Answer 1

After some research (we may have a similar situation, it seems that blazeDS is not able to use NIOs. Here is a link about it. They offer a solution that seems broken with newer versions of tomcat. So I guess blazeDS is not the one to use in your usecase.

If you cannot go with LCDS, a good free solution is graniteDS, supporting asynchronous servlets
