Subject Re: Increase transaction throughput with nodes.
Date Tue, 07 Jun 2016 10:55:37 GMT

Your understanding is correct. The overall throughput should grow if you
scale horizontally.

However in case of distributed transactions many factors can be a reason of
why the performance doesn't grow significantly:
- the same locks are held by multiple pessimistic transactions;
- CacheConfiguration.setMaxConcurrentAsyncOperations is reached;
- transactions are mostly executed on a subset of nodes;
- etc.

In general also you may want to use optimistic transactions that work faster
in some cases.
