We consider to use "Distributed ImpEx" in our project, and I read the page on help : https://help.hybris.com/6.4.0/hcd/3e0138c9bfc642349cad227cfcd72d9f.html
In this page, I see a property "impex.distributed.batch.size" to set the batch size which default is 100. Now we are trying to find the best batch size for our project in order to get better performers by tuning it on our test environment.
Is there any idea to estimate the optimum batch size(etc. memory size, CPU , cluster size)?
