What do I do when GateKeepers performance slows down when there are a large number of clients?
There are a few possibilities that could slow down GateKeeper when there are a large number of clients. One possibility is that, if all the clients go to a single server, the connection from the GateKeeper to the server might be congested. You can set the following properties to increase the number of connections from the GateKeeper to the server: vbroker.ce.iiop.cm.connectionSize Another possibility is that if servers take a long time to respond, the number of threads blocked in the GateKeeper might be too high. You can turn on the asynchronized IO mode in the GateKeeper to reduce the number of threads blocked for replies: vbroker.gatekeeper.asynchronziedIO=true We are currently looking into other ways, for example, native IO, to reduce the thread usage in the GateKeeper. When the number of the clients reach a point, you have to use multiple GateKeepers and do load balancing between them. From the benchmark test we did, we found the above two operations don’t have very much affect on
