Simultaneous Queries Execution Time (Minutes) I am facing a very weird proble. I have four different queries, each if executed individually will take say about 13 minutes. But if I execute them simulteneously (opening 4 different query analyzer windows and running one after another), it takes at least 36 minutes before the first one is displayed. I couldn't understand this behavior of SQL Server. Why it's taking soo much amount of time when parallel queries are executed? What exactly is going on?? I including all the possible details... Computer Specifications: OS: Windows 2K server Family SQL Server: Version 2000 RAM: 392 MB Processor:398 MHz And executed query from the same machine. I didn't use any remote client. Query 1 Query 2 Query 3 Query 4 CPU Elapsed CPU Elapsed CPU Elapsed CPU Elapsed Time Time Time Time TimeTime TimeTime 4.5443.17 4.5742.46 4.4737.69 4.3536.26 (4 queries simulta) 5.1335.75 5.2234.84 5.4331.32 (3 qrys simultansly) 4.0622.82 3.9522.16 (2qrys simulatenio) 3.5812.86 ( Singel Qry) Any Suggestions???
