Hi,

The maximum number of flow rules depends on the flow rules:
* which item and action types are used
* what flow rule attributes are used
* what are the values in item and action data (rare case)

You can estimate on real HW using app/flow-perf.
It will also give you other useful figures,
like memory consumption and flow rule insertion/deletion speed.
