In a previous question, I asked how Geth's
--fast flag worked. I'm now moving over to using Eth, so my question is: is there an equivalent option to allow Eth to quickly sync the block data? If so, what is the syntax?
The c++ implementation does not yet have the fast-sync feature. It can be used to fast sync from, but it will not fast sync itself.
You can track the progress on implementing this feature on github.
