The use of hardware load balancers will not increase overall performance. IBM
® HTTP Server provides load balancing and is usually sufficient. (The Web servers are usually underloaded by Webform Server traffic alone.)
If your infrastructure already involves the use of hardware load balancers, you can use them in front of or in addition to IBM
HTTP Server, in front of the Front End Application, or in front of the Translator. If you are using hardware load balancers in front of the Translator, you must configure the hardware load balancers for session affinity.
