Of course you may have some reasons to use Tomcat or anything else (i.e. your stuff may have more experience at Tomcat etc.) However developers generally runs Jetty because it is default for Solr and I should point that Solr unit tests run against jetty (in fact, a specific version of Jetty) and well tested (if you search in mail list you can find some conversations about it). If you follow Solr developer list you may realize it for example: https://issues.apache.org/jira/browse/SOLR-4716 and https://issues.apache.org/jira/browse/SOLR-4584?focusedCommentId=13625276&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13625276can show that there maybe some bugs for non Jetty containers and if you choose any other container except for Jetty you can hit one of them.
If you want to look at the comparison of Jetty vs. Tomcat I suggest you look at here: http://www.openlogic.com/wazi/bid/257366/Power-Java-based-web-apps-with-Jetty-application-server and here: http://www.infoq.com/news/2009/08/google-chose-jetty On the other if you have any future plans for Solr you may want to look at a conversation for Solr: http://search-lucene.com/m/vsUcqf7VJ1/%2522VOTE%253A+solr+no+longer+webapp%2522&subj=Re+VOTE+solr+no+longer+webapp If we talk about JDK, I suggest you Oracle JDK. You may read an old message about it here: http://search-lucene.com/m/B06lalj3Xs/openjdk+or+sunjdk&subj=any+experiences+with+running+SOLR+on+OpenJDK+ 2013/5/11 Spadez <james_will...@hotmail.com> > Hi, > > I was wondering, what setup have people had the most luck with from a > performance point of view? > > Tomcat Vs Jetty > Open JDK vs Oracle JDK > > I haven't been able to find any information online to backup any sort of > performance claims.
