server bottleneck

[PaulW]

Thank you for your reply. I am attaching a screenshot of the VisualVM output showing high CPU usage by the PUMP POOLED threads and o.b.e.d and o.b.g.j methods. The method g.b.b.a also has a very high "Self Time" but does not appear to be the CPU bottleneck. I am using the latest version of Lightstreamer Moderato (Lightstreamer 6.0 b1 build 20140801). If you open the lightstreamer.jar file as a zip archive, the file /com/lightstreamer/o/b/e.class contains the method "d" and /com/lightstreamer/o/b/g.class contains the method "j". I am sending the ADD commands as real-time updates.
