I am using the performance monitor of Windows to see the values of the process
jrun, the result is the following:

handle count:1189 (max value ups to 1520)
thread count: 91 (max value ups to 420)

The values in jrun.xml

jrun.xml (proxyservice)
<attribute name="minHandlerThreads">1</attribute>
<attribute name="maxHandlerThreads">2500</attribute>

Is Correct?
