[julia-users] any clarification of bytes allocated in @time?

[John Drummond]

For the following code (julia 0.3.3 in windows 7 ) I don't understand what 
the bytes allocated in @time means

All I'm doing each time is adding 10  8 byte integers

Thanks for any thoughts

julia> @time c = [1,2]
elapsed time: 3.32e-6 seconds (144 bytes allocated)
2-element Array{Int64,1}:
 1
 2

julia> sizeof(c)
16


julia> @time for x in 30:39 push!(c, x) end
elapsed time: 2.717e-6 seconds (256 bytes allocated)

julia> @time for x in 30:39 push!(c, x) end
elapsed time: 2.717e-6 seconds (288 bytes allocated)

julia> @time for x in 30:39 push!(c, x) end
elapsed time: 2.112e-6 seconds (0 bytes allocated)

julia> @time for x in 30:39 push!(c, x) end
elapsed time: 3.321e-6 seconds (640 bytes allocated)

julia> sizeof(c)
336
