I doubt this is your issue, the garbage collector will run automatically at need.
What happens if you do a full import, stop and restart your Solr server and then try the delta? If the delta takes an hour then it has nothing to do with garbage collection. What are you importing from? I'd suspect that your problem is more along the lines that your extraction process somehow takes a long time to just extract the data and Solr is a red herring...
