Re: [rules-users] parallel folw execution
The process engine really doesn't add that much overhead to the actual
work that needs to be performed by the process itself. If you're
invoking a service that takes 2-3 seconds, you need to make sure you
invoke the service asynchronously, so the engine can continue executing
other process instances while waiting for the results.
In general, you usually start with one session running your process
instances in parallel on one CPU. This scales as long as the CPU is
capable of doing all the work + some overhead. It is trivial to scale
to multiple sessions (possibly on multiple systems) afterwards.

Quoting borg <nborgix(a)gmail.com>:
How would this scale?
Having in consideration that:
- I would end-up with 20-30 flows and
- each flow would would have an event hit rate of 15/sec and
- each flow would last for an average of 2-3 sec
We can imagine an average of ~1000 flow instances running at any
given time.
Assuming fairly simple flows and respective components (also
containing
rules), would the engine cope well with such load scenario?
(ex. HW 2x4c CPU; 32GB RAM)
Thanks
