Zhang: In 3.6, there's really no choice except to load all the cores on startup. 10 minutes still seems excessive, do you perhaps have a heavy-weight firstSearcher query?
Yes, soft commits are 4.x only, so that's not your problem. There's a shareSchema option that tries to only load 1 copy of the schema that should help, but that doesn't help with loading solrconfig.xml. Also in the 4.3+ world there's the option to lazily-load cores, see: http://wiki.apache.org/solr/LotsOfCores for the overview. Perhaps not an option, but I thought I'd mention it. But I'm afraid you're stuck. You might be able to run bigger hardware (perhaps you're memory-starved). Other than that, you may need to use more than one machine to get fast enough startup times.
