The purpose of this group is to share and spread information about various technologies, technicques, involved in tuning any web application. Though we may talk about Java, J2EE examples more, in the beginning, Performance tuning usually is, technology agnostic. We will talk about various components involved, that contribute to the performance of an application like, Database, Middle tier application servers and front end web servers like Apache, IIS etc. We may also talk about the security layer components like LDAP servers, and proxies. We can talk about Global load balancers and various network tools that may help find the performance bottlenecks. We obiviously will talk about tuning techniques available with standard Java and J2EE frameworks. Bottom line is we need not limit ourself, since performance tuning is a broad technology after all.
