I replicated this and I am not seeing a benefit. I have put the pool.protocol into
the setupEnvironment - no difference. Any thoughts on this?

i checked out subject_031. modified JNDISourceAdapter. rebuilt with ant dist - copied
the jar file to ldappc and grouper and ran both - watched the logs - i don't see efficient
pooling going on. i see connection, bind, unbind and drop. and it is still slow.

pointers appreciated.

environment.put("com.sun.jndi.ldap.connect.pool", "true");
environment.put("com.sun.jndi.ldap.connect.pool.protocol", "plain ssl");
environment.put("com.sun.jndi.ldap.connect.pool.initsize", 5);

Hi Michael,

I added the following line of code in the setupEnvironment() method of the JNDISourceAdapter class.
environment.put("com.sun.jndi.ldap.connect.pool", "true");

Then since I'm using SSL, I added the following to the java command line.
-Dcom.sun.jndi.ldap.connect.pool.protocol="plain ssl"

Shilen,

How did you enable connection pooling? Did you do something equivalent to
adding -Dcom.sun.jndi.ldap.connect.pool="true" to the java commandline? Or something
else?

Hello,

I recall the connection pooling issue with the JNDISourceAdapter being brought up before, but I don't see any Jira issues on that. So I thought I would share some results. Simply by adding connection pooling to the JNDISourceAdapter, I'm seeing a significant performance improvement while making repeated calls to Member.getSubject(). For instance, for a group with 120 members, retrieving the Subject objects for all 120 members resulted in a 60% performance improvement while using connection pooling.
