[...] centralized exchanges still are faster at executing transactions, by orders of magnitude in general, than decentralized ones. So there are places for both kind of exchanges.

I fully agree.
High frequency trading will by design be impossible with B&C Exchange - at least in the implementation that is currently being created.
I have no idea how to bring the speed of a decentralized exchange even close to a centralized exchange, but doubt that it's possible with the currently available tools.

This decentralized exchange is going to have other benefits than speed (just to name a few):

ability to trade native assets instead of proxy assets (in difference to other decentralized exchanges, same as centralized exchanges)
high level of security due to multisig with different possible levels (rarely (if ever!) found at centralized exchanges)
high level of availablity - all trades happen on blockchain and cost BKC; DDoS'ing the blockchain is possible, but very costly as BKC are required for it
highly flexible ways to access the "account": by wallet application on own computer or through websites, which offer access to the blockchain
leveraged/margin trading is basically possible
decentralized escrow services are within reach
