Re: Test environment is a single server - live is a cluster
It always best to have you DEV/TEST environment mimic you PROD / live environment. However, I can't say for sure that you will experience exactly from DEV to PROD since both environments are different, but the only thing I might say that can give you a hit by comparing a 2 nodes cluster to single node would be the performance. Lets see if anyone else have any other inputs.
