Well, with Lucene it is an API call in the same JVM in the same web
application. With Solr, you are making HTTP calls across the network,
serializing requests and de-serializing responses. So the comparison is not
exactly apples to apples.

Look at what Solr offers -- replication, caching, plugins etc. Will you
really need to go over 2500 requests per second? Do you need to be concerned
with performance above and beyond that? Will it be easier to scale out to
more boxes?
