: 1) how are you timing this (ie: what exactly are you measuring) : And I got the time from dispatchfilter received the request to : responsewriter write the response : It is much larger than QTime.
can you be more specific about what you mean when you say "And I got the time from dispatchfilter..." What *exactly* are you looking at (ie: is this a time you are seeing in a log file? ifso which log file? ... is this timing code you added to the dispatch filter yourself? what *exactly* are you looking at?) I ask because it's possible there is included network IO overhead in communicating with your client (i would be suprised if it was significant if you are only returning a single field for the first 50 results, but i know nothing about your network setup, or what your client code look ike -- so anythign is possible. : 7-9 fields : only one of the fields is text, rest of them are short string or int ... How big is the text field? Are you talking about a few hundred chars or several KB of text per doc? Is <enableLazyFieldLoading> set to true in your solrconfig.xml? (I forgot we had that option when i sent my last email, as long as you are using the "fl" param with just your uniqueKey field document retrieval should be "fast enough" and fairly consistent. -Hoss
