Kevin Ford has run some performance tests and reported the results: http://windingroadway.blogspot.co.il/2015/02/mobile-development-platform-performance.html

I converted the tests to B4A and B4i.

The results are:
1. File size
B4A - 112KB
B4i (32 bit + 64 bit) - 447KB

The tests were made on Nexus 5 and iPhone 5S in Release mode.
2. Load times for both were less than one second.
3. Adding 1000 records.
It is a programming mistake to add 1000 records without creating an explicit transaction (as implemented by the blogger).
With transactions:
B4A - 0.16 s
B4i - 0.1 s

With no transactions:
B4A - 9.5 s
B4i - 12 s

4. Reading records to ListView / TableView:
B4A - 0.02 s
B4i - 0.02 s

5. Writing to a file:
B4A - 0.01 s
B4i - 0.02 s

6. Reading from a file to ListView / TableView:
B4A - 0.01 s
B4i - 0.02 s

Note that the B4i project uses a new library that wraps the native UITableView (iTableView). It will be released next week.

The performance of both B4A and B4i is similar to the performance of native apps.

Looks like you've nailed it Erel :) Congratulations. Perhaps you should ask him to include the results in the Blog.
