WebSphere Host On-Demand
Redirector load capacity recommendations


You can use the following information as a guide for estimating the load capacity of the Host On-Demand 8 Redirector on AIX and Windows. Actual numbers may vary, depending on the following factors: hardware, network traffic, server load, and the frequency of session establishment.

On average, the Redirector established 13 connections per second. Each established connection then started a new transaction (data sent) 1/10 of a second after the previous transaction ended (data received). Most services and programs were stopped on the test machines, including the Web servers.
