I heard Java Compute node is much faster than normal COmpute node?

Is this correct? if so why?

heavy processing/transformation is light wrt JCN then doing it in eSQL....
as java processing is faster...

but JCN consumes time wrt entering and exiting the message.. so having too many JCN's in you flow is not considered a good idea..

performance wise JCN is not good, it carries JVM along with it to broker

but some what ok on V6.1

ESQL good in performance wise...

Follow this.
It will show you the throughput achieved using JCN and Compute Node.
Use Compute node af far as we can and if something we can't do using it then go for custom JCN.
