: In my Mac OSX when starting Solr as OOTB, : I always have to wait 30 sec for completely loading. : It seems that loading SolrInfoMBeanHandler is slow in Solr 4.x (also 4.5).
Are you certain the problem is coming from SolrInfoMBeanHandler and not one of the other admin handler rleated classes? I suspect you are seeing slow DNS resolution due to badly configured hostname for your system. Solr tries to cache this info, but the first time it tries to resolve the hostname can still cause a block on startup (or core reload) if your DNS isn't configured properly. Some background can be found here in an issue proposing that this be done entirely in a background thread... https://issues.apache.org/jira/browse/SOLR-5043 : Does anyone have the same problem? : : : : log: : DEBUG - 2013-10-16 00:51:14.144; org.apache.solr.handler.component.SearchHandler; Adding debug component:org.apache.solr.handler.component.DebugComponent@584391f0 : DEBUG - 2013-10-16 00:51:14.151; org.eclipse.jetty.webapp.WebAppClassLoader; loaded class org.apache.solr.handler.admin.AdminHandlers$StandardHandler from WebAppClassLoader=1510130526@5a02c35e : DEBUG - 2013-10-16 00:51:14.158; org.eclipse.jetty.webapp.WebAppClassLoader; loaded class org.apache.solr.handler.admin.LukeRequestHandler from WebAppClassLoader=1510130526@5a02c35e : DEBUG - 2013-10-16 00:51:44.166; org.eclipse.jetty.webapp.WebAppClassLoader; loaded class org.apache.solr.handler.admin.SolrInfoMBeanHandler from WebAppClassLoader=1510130526@5a02c35e : DEBUG - 2013-10-16 00:51:44.168; org.eclipse.jetty.webapp.WebAppClassLoader; loaded class org.apache.solr.handler.admin.PluginInfoHandler from WebAppClassLoader=1510130526@5a02c35e : DEBUG - 2013-10-16 00:51:44.169; org.eclipse.jetty.webapp.WebAppClassLoader; loaded class org.apache.solr.handler.admin.ShowFileRequestHandler from WebAppClassLoader=1510130526@5a02c35e : : : : : : : INFO - 2013-10-16 00:51:44.499; org.apache.solr.handler.component.SpellCheckComponent$SpellCheckerListener; Loading spell index for spellchecker: default : INFO - 2013-10-16 00:51:44.499; org.apache.solr.handler.component.SpellCheckComponent$SpellCheckerListener; Loading spell index for spellchecker: wordbreak : INFO - 2013-10-16 00:51:44.500; org.apache.solr.core.SolrCore; [collection1] Registered new searcher Searcher@3b46ad8b main{StandardDirectoryReader(segments_1:1:nrt)} : DEBUG - 2013-10-16 00:51:53.870; org.eclipse.jetty.http.HttpParser; filled 402/402 : DEBUG - 2013-10-16 00:51:53.882; org.eclipse.jetty.server.Server; REQUEST /solr/select on BlockingHttpConnection@4302df5,g=HttpGenerator{s=0,h=-1,b=-1,c=-1},p=HttpParser{s=-5,l=23,c=0},r=1 : : : : Regards, : Shinichiro Abe : : : -Hoss
