PS4, Line 29:  Saw significant improvements:
yeah, I don't think that we should put more effort to the investigation 
(revert), it is just a bit sad that we had the right benchmarks to catch this, 
just didn't run them

> We need to improve the job to support larger scale factor

For these kind of tests we could also get large row numbers by cross joining 
with another table, so the actual data on disk wouldn't need to be large.
Another thing that could help is is checking some specific counters in the 
profile.e.g the sum of MaterializeTupleTime if the function is used in WHERE.
