| When you say it "responds slowly" - what do you mean? Is it a specifi query - or something else you are trying to do?If you could post some extra detail pleaseJack Vamvas--------------------http://www.ITjobfeed.com |

| 1)Have you checked that there aren't any processes on your server using excessive CPU , or other resources?2)Are there any jobs , or background activities on the errant instance?3)Have you allocated sufficient resources for the third instance?Check in the memory options?Jack Vamvas--------------------http://www.ITjobfeed.com |

| Have you checked in Activity Monitor for that particular instance ? are there any open transactions?Could you post the Min server memory and max server memory of that instance , and is that similar to the other instances?Also could you let me know the physical memory of the server.The tests that you are running across the 3 instances , are they the same?. If not , could your try running similar tests across the 3 instances .Which sql server edition are you running?Jack Vamvas--------------------http://www.ITjobfeed.com |

| How are you connecting to each instance? TCP IP with different ports? |

| I would suggest giving each instance a specific port, try connecting to it via IP:PORT 192.168.0.2:1434 192.168.0.2:1433 etc |
