Couple of days ago I found know of the OHS feature i.e can make multiple instances. I'm wondering,if using multiple cases of OHS webserver boosts the performance from the Webserver.

Can there be any advantage, apart from less server space use for implementing multiple cases of OHS?

Where this feature of OHS can be used?

TIA Anil

Appears that primary advantage would be to eliminate single reason for failure situation. If one of these in some way crashes, others continue running.
