The config for the included Jetty has had a small amount of tuning done specifically for Solr. You would lose that if you switched. Also, the Jetty included with Solr has had a bunch of the jars and their configuration stripped out. That makes it use less memory, and likely run a little bit faster. > Also, as support for deploying Solr as a WAR in standalone servlet > containers like Jetty is no longer supported from Solr 5.0, is it still > possible to deploy Solr using an external copy of Jetty? Although we don't recommend it, for now you can find the .war file in the download and deploy it in other containers. That will be changing in a future release, but we don't have an ETA. There is a wiki page discussing the situation. It is still a work in progress: https://wiki.apache.org/solr/WhyNoWar Thanks, Shawn
