Hi all;
Even having a lot of memory (no memory leak in the JVM heap size and stack thread size) , a most idle processor (~ 60-70% idle ) and also a network bandwith of 35-40 Mbit/s in which it's capacity is 100 Mbit/s , when i increase the additional instances , the performance degrades. Can any body find any relationship? The flow contains only one input node and additional instances is increased form 16 to 32.

Network may only be one of the bottle necks... Have you checked paging, IO limitations at the Data storage level, nic card etc...

Have you checked simple things like the TCP/IP Negociation parmeter? The default is often 'Autonegociate'. That means that every packet goes through a negociation.
Then there is the mode. Half or full duplex?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.
