I just saw another part of your message, I am wondering also why memory
consumption is so high.

Besides Julia internals, I suppose there is memory overhead in terms of the
structure holding the array itself (when temporaries are created).
I suppose an array isn't just the size in bytes of the data it holds, but
also information about its size/type/etc. Though I doubt that would add up
to
That overhead seems constant, beyond a single temporary. So I dont suppose
there is that much to be worried about, unless you are using many small
arrays.
julia 800-sizeof(rand(2))

julia 944-sizeof(rand(20))

Avik: this is actually the situation I'm in. My tight inner loops
involve elementwise operations on many small arrays, so the runtime cost
of using vectorized code is enormous. Using the macros provided by
Devectorize.jl only somewhat alleviates this problem, so I ended up
hand-writing
