I don't know why reading speed is that slow in your case, especially
as you are using AES-NI, which should give you the highest speed
available. Maybe others here on the list have a suggestion. Probably,
you should provide some more information.

Otherwise, on the newer Intel i3/i5/i7, twofish-3way is faster than
AES. You could try to re-format your drive with twofish-xts-plain64
and adding twofish_common, twofish_x86_64 and twofish_x86_64_3way to
your initram (as long as your kernel is built with these enabled).
