Tune the persistent connection settings for ODR performance to minimize time spent in setting up new connections and taking down older connections during a barrage of requests. Primarily, this tuning is relevant to the connections between the ODR and the application servers.
Modify your JVM heap settings. See Modifying the JVM heap size for the on demand router .
Adjusting the application server's maximum persistent requests lets the ODR reuse the connection to the application server for as long as it can. To do this, adjust the ODR settings in the transport chains. You should set it high enough to avoid having to bring down and recreate a connection during a barrage of requests, so set the value to at least the number of requests in a single barrage of request. The barrage can be a single page with associated datat with a long think time, or a series of pages and associated data in short succession. If you set a value high than this, it will not negatively affect performance provided the persistent timeout is set appropriately to close idle connections.
The following steps show you how to adjust the application server's maximum persistent requests per connection.
