Thanks Hoss, My system seemed to configure bad DNS setting. I used Google Public DNS instead then Solr started up quickly. I'll try to confirm DNS configuration properly.
SolrInfoMBeanHandler was not slow, but SystemInfoHandler.init() before SolrInfoMBeanHandler was slow, I think. So SOLR-5043's background thread solution is good.
