Index rebuilding results in increased performance?

Alfresco,

We are running performance tests on our Alfresco 1.4.3 Enterprise server and needed to rebuild the indexes (for some unrelated problem). After this we noticed an incredible performance increase. Our test plan runs 76% faster now. The test plan simulates a user that visits a website based on Freemarker templates on top of Alfresco (based on quite a few Lucene searches).

Is it possible that the indexes get cluttered after a while? Is it worth running a full index rebuild every x months on a production environment to keep the performance up?

Thanks!

Hi

It is possible this is down to keeping some information about rolled back transactions until the server is restarted (which has been removed). Does simply restarting give the same improvement.

Without having the index structure and info file it is difficult to say for sure.

I have only seen this issue for heavy FTP use which seems can end up with a few rolled back transactions.

Andy, thank you for the feedback.

Restarting the server does not give the same performance increase, index rebuilding does so I don't think it has anything to do with the transaction rollback.

We are not havy FTP users but CIFS is used more often, could this explain anything?

Where can I find the index structure and info file? Can I send you the indexes folder?

Hi

The best way to sort this out will be to get in touch via support.
