Damn you 😡 It is still going. You were right and I remembered it wrong. I've dug out a 15 months old results of full sync and it was running over 37 hours up to 72M+. Compared to that current version appears to be slightly faster, but still couple times slower than what I thought it would be.
To be honest it smells like a bug (or more optimistically - as an optimization opportunity). There are couple of hiccups when node is not receiving blocks fast enough, but for the most part block processing is reported at close to 100% time. On the other hand computer seems to be sleeping, using around single core only, which is weird, since decomposing signatures, that used to make sync 7 times slower than replay, since HF26 is supposedly done on multiple threads and preemptively, as soon as block arrives, so I'd expect at least some bursts of higher CPU activity. Maybe I should use some config option for that?
It would be nice to have a comparison on the same machine: pure replay vs replay with full validation vs sync.
