Jackrabbit-RMI performance problems

[Kevin Pfaff <ke...@byteconsult.de>]

Hello -
 
I have a little problem with the performance with jcr over rmi on different pcs. We have the same jackrabbit-standalone (version 2.2.7) running on 3 different pcs. Two of them are the same pcs (hardware) and one is more powerful. The access speed on the more powerful one and one of the other two is much slower (1-2 accesses per second) than on the third one (more than ten). We use the exact same jcr-standalone (version 2.2.7), operating system (windows 7 sp1), Eclipse version (indigo),  jdk (1.6.0_26) and program (the one we are developing). Anybody some suggestions?
 
Thanks,
Kevin

AW: Jackrabbit-RMI performance problems

Hi,

I now can pinpoint the problem after some testing. The reason for the long access times comes from the login. I stopped time for this code:

		Credentials credentials = new SimpleCredentials("Test", "test".toCharArray());
		this.repository.login(credentials);

The repository comes from Spring IDE with autowire and the setting for the repository are the same for all 3 pcs. The fast pc needs for this little code about 5 milliseconds the other two need over 500 ms. We even tried to connect to the repository of the "fast access pc" over network, but still the same results, it is only fast for itself. Some suggestions?

Thanks,
Kevin

The servers (jackrabbit-standalone) are running on localhost on all three pcs each. The programs are running on tomcat 6 in eclipse and connect to the jackrabbit-standalone on the same pc.

Sounds like differences in RMI or network configuration. Have you
traced the network traffic between the RMI client and the different
servers?
