Hi All,


I ran these tests several times, and each time I come back with the similar 
results. I really don't get it. I am using JDBC sampler with max connections 
set to 30 for running across 3 machines and 90 when running on one machine. 
Here's the results:


30 Threads x 3 Machines for 2 minutes




















Number of Samples: 176,912

Average Response: 62

Std. Deviation: 436.46%


90 Threads x 1 Machine for 2 minutes




















Number of Samples: 912,954

Average Response: 11

Std. Deviation: 34.14%





Machine Specs:

RAM: 8GB

Processor: Intel Core i7 CPU     870 @ 2.93Ghz

System Type: 64-bit Windows 7



Any idea why I see this huge discrepancy? I have double checked on our database 
on the server side and I verified that we do have the number of connections we 
expect to see, but I can't understand why the performance looks so lousy with 
multiple machines.





Thanks,
James
