I was doing some performance testing using JRun 4. I have a stateless
session bean deployed on a server running JRun 4. The session bean does a
simple insert into an Oracle DB. I have a CF page talking to the session
bean remotely. It appears that it takes 9 seconds to insert a row into the
table. Now I ran the same test locally with the bean deployed in the same
instance that the client CF page is deployed in. The results of this test
were 21 seconds for a 1000 inserts. If I run a 1000 tests remotely it would
take 2 and a half hours at 9 seconds an insert. I have tried to run this
test and about half way through the test I get the error below. I know the
problem is not within the network cause I have made a simple stand alone
java application that performs the 1000 inserts in about 120 seconds. Also
I have tried a jsp and a servlet both of them return an insert in 9 seconds
so that rules out CF. Does JRun 4 have any settings that may increase its
performance? Here is the error. Clustering in the jrun.xml is not enabled.
