Hi Eric, Thanks very much for helps (I should have responded sooner):
1/ My problem in 3.6 turned out to be much related to the fact I did not share schema, after using shareSchema, the start time is reduced up to 80% (to my great surprise, previously I thought burden is most in solrconfig). 2/ I just upgraded to solr 4.3, but somehow I did not see all the fixes mentioned in the WIKI (like shareConfig), I saw the resolution is "Won't fix", do you have plan to put the fix into next release?

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.
