That'll let you be sure that you have a precise copy of the data, the structures, statistics, indexes, etc. Then, any differences are likely to be caused by hardware; memory, cpu or disk.</description><pubDate>Fri, 13 Mar 2009 10:30:08 GMT</pubDate><dc:creator>Grant Fritchey</dc:creator></item><item><title>RE: Server Comparison</title><link>http://www.sqlservercentral.com/Forums/Topic675195-360-1.aspx</link><description>The query plans are indeed different. The actual plan on TEST has a nested loop, an index scan and a key lookup. The actual plan on BISQL parallelism and a table scan. So the reason for the longer elapsed time with the shorter cpu time might be I/O? They both produce the same amount of records</description><pubDate>Fri, 13 Mar 2009 10:06:24 GMT</pubDate><dc:creator>Andrew Hartnett</dc:creator></item><item><title>RE: Server Comparison</title><link>http://www.sqlservercentral.com/Forums/Topic675195-360-1.aspx</link><description>CPU time is not the only metric, don't forget I/O as well.   Have you tried looking at the actual query plan (not the estimated one) for the query on each server?  If so is there a difference?</description><pubDate>Fri, 13 Mar 2009 09:04:58 GMT</pubDate><dc:creator>Henry Treftz</dc:creator></item><item><title>Server Comparison</title><link>http://www.sqlservercentral.com/Forums/Topic675195-360-1.aspx</link><description>This is my first post on here so bare with me. I have a sql query that I have run on two different servers. I am trying to get some performance metrics so I can see which server has a better architecture. The only thing that I do not understand is that the TEST server has a smaller elapsed time but has a longer CPU seconds/Iteration Avg. It would seem to me that if the cpu time is longer that the elapsed time would follow the same trend. Any ideas as to why this is would be helpful.
