Hi all, I have some problem of performance during the execution of ATL
higher-order transformations: they take about one/two minutes to finish.

My ATL transformations are composed of:

- amw and emf handlers for input models

- approximately 20 rules

- 20 helpers

- 1 entrypoint rule

- 1 endpoint rule (with 20/30 calls to the inject("OUT", "ebnf2", ...)
method)

- about 30/35 calls to thisModule.ResolveTemp

- almost every rule contains a call to some element of the input metamodels
(i.e. MOF!EModelElement.getInstanceById(modelName,classifierID))

- about 10 calls to the inject("OUT", "ebnf2", ...) method

Does anyone know how ATL virtual machine handles such type of
transformation, where is the bottleneck, and how to make a better
performance tuning of my transformation?

Thank you, Ivano

Hi,

Have you tried to run it on the new emf VM ?
