I have been running Solr 4.10 with Tomcat 7 with manual shard scheme (i.e. 4 Tomcats with 16 shards - Each tomcat having 4 contexts / instances in it to represent shards). It was working fairly good for last 4 years, but with few OOM (Out of memory) on random servers. This situation get back normal, if I schedule a random server restart. I have been using distributed search feature; which disallow me to use Solr Cloud.
Each shard is pointing to separate folders. In migration to Jetty; it appears as a surprise that it support single shard per Jetty server. In order to test this one further, I created 16 servers for all and bench mark. Jetty / Solr performance is slow than Tomcat / Solr performance, which is a surprise. tomcat is 25% faster than jetty. I am sure; I am missing something otherwise Solr team might not be recommending Jetty for 5.X versions. Q: Is this a normal that one node support one shard in Jetty? Q: Can anyone point to appropriate guideline; if jetty is better than tomcat? Q: Have anyone else experienced similar migration, and concluded that tomcat is better. Thank you, Have a great day !
