Pradeep,



Even though you did not provide any details on how you measure the throughout, 
I think the drop is expected. It is because as soon as a second (and the third 
and so on) node joins the Ignite cluster, most of Ignite operations become 
distributed and involve remote calls.



There are ways to minimize the performance impact -- for example, ensuring that 
the processing is colocated with the data to be processed as opposed to bring 
the data to a single processing node, etc -- but in all cases it's very 
application specific.



Regards

Andrey

No, I mean I have one ignite instance running in one JVM and there are several 
application JVMs that have one embedded instance on each of them and they all 
talk to each other.

Hi Pradeep,

Why did you start several Ignite instances in one JVM?
AFAIK it is recommended only for testing.
In production it is recommended to start separate JVMs.

Hi,

I am seeing a big drop in performance when more two or more ignite instances 
embedded within JVMs form a cluster. The throughput I get is 1/10 of what I 
used to get when working with only one embedded ignite instance inside the 
application.

Can anyone help me in tuning this thing?

Thanks,
Pradeep V.B.
