Subject Re: [jira] [Commented] (SOLR-4112) Dataimporting with SolrCloud Fails
Date Thu, 10 Jan 2013 12:17:18 GMT

When you say the index went from 14G to 7G, did you notice whether the
difference was tin the *.fdt and *.fdx files? That would be due to
compression of stored fields which is now the default.... If you could,
would you let us know the sizes of the files with those two extensions
before after? I'm trying to gather real-world examples...

But about your slowdown, does the same thing happen if you specify
&fl=score (and insure that lazy load is configured in solrconfig.xml)? I
don't think that would be reading the fields off disk and decompressing

what are you measuring? Total time to return to the client? It'd also help
pin this down if you looked just at QTime in the responses, that should be
exclusive of time to assemble the documents, it's purely searching.
