Load balance is not even although using Leastcon + cmp disabled + no oneconnect

Hi everybody

 

I've config vs with source persist and have pool with 2 member

 

And I perform load test from 10 Machine (10 IP) with the same script.

 

The result is not good because statistic show that server-1 have more stat than server-2 (around 70%/30% sometimes 60%/40%)

 

I not sure why it's not even

 

we config standard vs with cmp disabled and LB with Least connection method. no oneconnect. using source persist

 

this should balance 50/50 or at least 45/55

 

Is there a theory that explain why this doesn't even? I think SOL10430 is not support this case.

 

Thank you very much
