Starting from version 9.4.0, you have two processing engines, Standard and Piranha. Standard is the current open-source engine included in FreeEed. Piranha engine gives a 5-10 increase in processing speed and unlimited scalability if multiple computers are available. The choice is in the project’s settings.
If you choose the Piranha processing engine, you need to supply parameters.
For using the Piranha engine, you will need the runtime, the license, and likely support in setting it up.
