[flexcoders] Streaming BlazeDS connection reverting to polling
I know there is a hardware imposed limitation to the number of BlazeDS real-time streaming connections that you can establish. I've heard it's in the hundreds, so I'm trying to see how many I can connect to my server(WinXP Pro 64-bit with two 3GHz Xeon CPUs and 8GB of RAM). Oddly enough after the 10th client logs in, all subsequent logins revert to a polling connection. Is there some limit on the number of streaming connections you can have before they fall back to polling? Something else I'm missing? BTW, even with polling I can establish 200 connections and the server barely blinks except for an increase in CPU usage due to all of that polling. Thanks, Geoff

It is 10 - please check the source of the BlazeDS source - can be increased to few hundreds in your configuration but you might want to consider setting process affinity and set up LCDS 2.6 express NIO HTTP adapter to really scale it up. Other option is to modify BlazeDS code to not keep the connection and enable NIO adapter on WebContainer/ move connection management into the custom endpoint - then you can scale blazeDS up to few thousand connections.Regards, Anatole Tartakovsky On Thu, Jun 5, 2008 at 5:03 PM, Geoffrey [EMAIL PROTECTED] wrote: I know there is a hardware imposed limitation to the number of BlazeDS real-time streaming connections that you can establish.

Re: [flexcoders] Streaming BlazeDS connection reverting to polling
Another option would be to use WebORB. The more I look at what WebORB can do, the easier it is to pick it over other servers. We just had a WebORB presentation at our UG meeting on Tuesday. If you haven't looked at, you should.
