Here is the comparison / benchmarking of:
1) current package
2) current package + attached debdiff
3) upstream code

It shows that:
1) performance of current package improves a *lot* with the attached debdiff;
2) performance of current package + attached debdiff is equal to the upstream's.


$ openssl speed -evp aes-128-gcm
--------------------------------

1) current package

	$ openssl speed -evp aes-128-gcm
	<...>
	The 'numbers' are in 1000s of bytes per second processed.
