Could you please link to the technical reviews you mentioned? I would be very interested to read them because as an outsider, Flash Boys seemed overly simplistic, but I haven't been able to figure out what the real story is yet.
Again: a single positive technical review would be interesting. I'm not being hyperbolic: I haven't read a single one. The sense I get is that everyone who's ever formatted a FIX message thinks _Flash Boys_ is terrible.
