One more thing. When I do the same grinder setup just calling the services directly from a java class (just like I do in the service tasks in activiti) I can get 20 TPS. With activiti I get 8 TPS.

- You're not using a connection pool. SimpleDriverDatasource is NOT adequate for real scenarios.

If you can only get 20tps without activiti, this means you got some 'heavy' logic. You're blocking transactions with this heavy logic. Think about a pub/sub mechanism to take the load out of the transaction.

Is there a doc on Activiti Best Practices For Production?

No, it's also really hard to write a generic doc like that. It depends on a lot of parameters.
But could you respond to Joram's post? Do you have heavy logic in your process definition?
Because Activiti should not add much delays itself.

Hi,

Changing the datasource to one that used a connection pool solved my problem. After doing that activiti added very little overhead.
