Yurii Zubrytskyi 8ee7b1191a [zip] Stop calculating crc if it's not checked 
Crc calculation shows up in the profiler in 2-5% range, and is
never currently validated. Let's disable it for good.
For a well-compressible test data the difference is even nicer:

Benchmark                       Time          CPU        Iteration
