ManifoldCF CMIS job slowing down alfresco drastically.

[lalit jangra <la...@gmail.com>]

Hello,

I am using ManifoldCF 1.7 with PostgreSQL 9.1 to connect to alfresco using
CMIS connector. I have customized connector to get fields i need and map
these fields to solr schema.

As i am testing with alfresco having around 50000 documents, i found when i
run alfresco job, as job progresses, alfresco slows down and users working
on alfresco can not work due to slowness. This slowness continues until job
finishes and once job finishes, alfresco is back to normal.

Please suggest for any performance tuning.

Regards,
Lalit.

Hi Lalit,

This is not ManifoldCF performance tuning you need -- it's Alfresco
performance tuning.

You have two choices.  The first is to figure out why Alfresco is getting
slow, and fix that.  It is likely to be resource starvation, e.g. too
little memory or insufficient processor resources. But that is something
that this project really can't help you with.

The second is to throttle back your CMIS connection.  See:

http://manifoldcf.apache.org/release/trunk/en_US/end-user-documentation.html#connections

... and look at the "Throttling" tab.  I would suggest trying to limit the
number of Alfresco connections to maybe 3 first and see whether that
helps.  If that's not enough, you can limit the rate at which documents are
fetched by adding a throttle on the same tab.  The bin regular expression
can be left empty to match all bins.
