[erlang-questions] Managing a huge binary file

[Max Lapshin]

It is a myth that mmap helps you to read file faster.

I've believed in this myth and packed mmap.erl with erlyvideo. But later it
happened that 3 Gbps are served from disk with plain file:read and mmap is
MUCH worser because it breaks scheduling.

So, file:read can give you several gbps.
