Apache-Tomcat Clustering

This parameter is the one that is taken for granted in the current era. All applications are assumed to be stable enough to work 24×7, 365 days a year. This is considered as the assumed parameter of measurement.

1). Scope

To ascertain that the parameters of speed, concurrency and stability are handled when an application […]

Tuning Apache + Tomcat

ATG: Tuning Apache + Tomcat

I did some tuning on Apache which vastly decreased response times.

The tests show increase vast decrease in response. (see table below) which is due to the following improvements made effective by the tuning (Increased maxclients, KeepAlive on. KeepAliveTimeout etc):

1) Reusable connections to handle multiple requests from the same […]
