Hi Chatzinikos , I've already changed that values while testing. But whatever you increase the maxThread number in server.xml, in flex applications, blazeds does not serve much more than a few hundreds connections. For LCDS,, whatever you increase the maxThread number in server.xml, LCDS does not serve much more than a few thounds of connections. This "a few hundreds connection" can be 700 maybe 800 depending on the application. And also this "a few thounds of connections" can be 5000,7000 or much more. I use blazeds. So my number assumptions about LCDS can be not too true. But a few thousands of connections is guarenteed for LCDS.
This is my experience, I think it can be useful for now and future, Best regards, Ali --- On Mon, 3/8/10, Fotis Chatzinikos <[email protected]> wrote: From: Fotis Chatzinikos <[email protected]> Subject: Re: [flexcoders] Exciting Load Test Results To: [email protected] Date: Monday, March 8, 2010, 6:14 AM There are probably 2 places you need to tweak in order to increase your concurrent connections: 1) server.xml for tomcat in the connector element the maxThreads param: <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" maxThreads="200" acceptCount="50"/> and 2) in proxy-config there is another setting that has to do with connections called max-total-connectio ns <properties> <connection-manager> <max-total-connectio ns>190</max-total-connecti ons> <default-max- connections- per-host>2</default-max- connections- per-host> </connection- manager> <allow-lax-ssl>true</allow-lax-ssl> </properties> I am not sure -yet- if the 2nd param has anything to do with your problem, as i have not load tested my app yet. Have a go with these and please let us know if you fix it it as i am sure many here are interested in these kinds of tests.

In my load test, when i load the server with 300 concurrent user giving AMF requests, the tool gives me [perm gen space errors],[java. io.IOException: Error writing to server] . The load test tool is soapui tool. I'm using apache tomcat app server. But when the concurrent user number is 100, there is no exception, it works well. So, i want to learn why i'm getting this error. Is there a peek number of concurrent user who send amf requests to the server? If it is, can we configure it from tomcat? Thnks.
