I got almost no experience with Solr, so please bear with me, if the answer is obvious:
In a Magento Enterprise 1.11 shop system (about 30k products), where one machine mainly serves the web requests and another machine is dedicated for database requests, does it generally make more sense to run a Solr daemon on the webserver machine, or on the database machine?
Can please someone explain me, whether it makes a difference and why?
