You cannot measure scalability of a database as such.  You need to
know the nature of the load (i.e. operations executed against the DB -
how many INSERT, UPDATE, DELETE and SELECT, against which tables and
with what frequency and criteria).  And then, as Sergey said, you need
to define whether you want to scale up the load or the size - or both.

Kind regards
