Additional Web Engine Question

Sorry if this in the wrong place, or answered elsewhere but i was unable to find it...

We have the following setup for our SolarWinds Orion:

1 - Main Poller/App Server

1 - Main SQL Database Server

1 - NetFlow DB Server

2 - Additional Polling Servers

1 - Additional Web Server

My question is, since we have the Added Web Server, should the SolarWinds Website service still be running on the main app server?  We point all traffic to the Additional Web Server.   Just trying to make sure there is as little overhead on each server to increase performance a tad.

Thanks,
