Subject [jira] [Created] (COUCHDB-1282) Allow special value 0 for os_process_limit
Date Wed, 14 Sep 2011 22:48:08 GMT
Allow special value 0 for os_process_limit

                 Key: COUCHDB-1282
             Project: CouchDB
          Issue Type: Improvement
            Reporter: Randall Leeds
            Assignee: Randall Leeds
            Priority: Trivial

It's unlikely to be beneficial to run more os processes than there are logical processors
in a system. It creates extra scheduling overhead if they are all in use. Currently default.ini
specifies 25, though the code specifies 10 if the option is missing, and I expect both are
too high for many real world deployments.

I propose the value 0 be used in default.ini and that it take special meaning: use the number
of logical processors erlang detects.
