The 7x speedup is in full sync of a node from no blocks all the way to head block, and it was measured on a normal consensus/seed node.

Note that "full node" is mostly a dead concept now, because full node normally implied an account history node which will be replaced by HAF account history app.

Now there is a "hived node with sql_serializer plugin" that feeds data to postgres, and I haven't done a benchmark for a hived configured this way with new code yet.

I'm running a few more sync benchmarks of various versions of the code this weekend (to determine which optimizations yielded which gains), and near the end I'll probably have time to try a full sync run with hived+sql_serializer (and probably a replay as well in this configuration).
