JRun fans, I am experimenting with high volume settings for JRun under
IIS. I seem to bump up against a limit of 1000 user threads open. I
have configured the default server SERVER-INF/jrun.xml as follows:
<service class="jrun.servlet.jrpp.JRunProxyService" name="ProxyService">
<!--<attribute name="activeHandlerThreads">25</attribute>-->
<attribute name="activeHandlerThreads">1005</attribute>
<attribute name="backlog">500</attribute>
<attribute name="deactivated">false</attribute>
<attribute name="interface">*</attribute>
<!--<attribute name="maxHandlerThreads">1000</attribute>-->
<attribute name="maxHandlerThreads">1005</attribute>
<attribute name="minHandlerThreads">1</attribute>
<attribute name="port">51000</attribute>
<attribute name="threadWaitTimeout">20</attribute>
<attribute name="timeout">300</attribute>
At 1000 concurrent connections the jrun server will start complaining
that I need to configure it for more threads. I can set the active and
or max handler threads higher, e.g., 2000, and it has no effect. When I
experimented with low numbers, these params normally allow me (N-1)
concurrent connections, where N is the HandlerThread param. Now from
what I understand, each socket connection will hold onto one thread, and
a VM on NT should be able to handle 2048 threads or so. Anyone have any
idea what I am missing?
I don't think IIS is the issue. But for what it's worth, I have JRun
connected to IIS5 on win2k server, which is configured to as follows:
100,000 hits per day
ListenBackLog 500
AcceptExOutstanding 200
MaxPoolThreads 20
PoolThreadLimit 2000
ServerListenBackLog 2000
MaxEndPointConnections 2000
Thanks for any advice. BenG.
