I guess most of this time was consumed on compilation of lib/registerTypes/* - they quite often need ~2 GB per file and in case of multithreaded compilation/low memory may cause huge slowdown due to swapping.

Frankly we have no idea what's causing this. So if you (or somebody else) will manage to fix this issue - this would be great.

For anyone who might be interested.

@AVS made interesting improvement for serialization:

For me this decreased compilation time from 4 minutes to 3 minutes.

It is obvious that the problem was in the hardware associated with a lack of RAM.
