Moreover, if you play with Nutch, you will see that's a rather complex and ambitious piece of software.  Solr is a lot smaller (code-wise) and simpler.  Again, it's hard to compare them, because they are really two pretty different things, even though they both do text indexing and searching.

overhead of the web-service submission not the backend or the functional 
differences.
