weblogic. problem of increase system performance in cluster.
Application servers Weblogic Cluster are installed on two physical machines.On each of them installed on the managed server. On managed servers deployed Web services that serve http requests (accept, validates, process and enters the information into the database).
We load many test-queries in a cluster through the balancer for performance testing.First, we include only one managed server, and then we use the two managed servers. The number of processed transactions does not depend on the number of managed servers in the cluster. In all cases, speed is about 800 tps. (???????)
We performed a similar exeperimental through a balancer. We sent transactions to the stub.The rate is much higher than 800 tps. Rate of passage requests through the balancer on stubs are much higher than 800 tps. Consequently, the balancer does not limit the speed of transactions.
