How much worse?

How many physical servers are in each configuration? How is each server 
configured in each, with how many data nodes? What kind of network? 
Gigabit?

Or was everything on one system? With virtual machines or without and 
just using different ports?

Are there errors in the log file (connection limits hit)?
