Xmpp pubsub => 20 % of the messages lost

Hi Everyone,

I am analysing the performance of openfire in single box scenario for xmpp “PUBSUB” i.e the server ,database,publisher and suscriber all located in the same m/c.

number of pub sub nodes
10
number of publishers
20
concurent publishers per node
4
number of subscribers
30
concurent subscribers per node
3
pub rate (mes per second per publisher)
7
execution time
600 seconds

The expected theoretical total number of messages : 252,000 i.e (number of publishers) x (pub rate) x (concurent subscribers per node) x (execution time)

Actual No .of Messages : 206,934.00
