Hi

in eZSolr::AddObject() we have:

    function addObject( $contentObject, $commit = true )
    {
    (...)
        if ( $commit )
        {
            // For every 1000 time, call optimize
            if ( mt_rand( 0, 999 ) == 1 )
            {
                $this->optimize();
            }
        }
    }

I think the running of optimize() should be controlled a bit better as it can cause a quite big burden on the server. For many setup's I would imagine that it would be way better to only run optimze() one or two times a day at dedicated times in an crontab.

It is also misleading that the $commit parameter actually runs an optimize() operation, and not only a commit().....
