mm(i::Int)=(a::Int,b::Int)->a*b #test1 @time begin gg=mm(10) for i=1:1000_0000 gg(10,10) end end # 0.091843 seconds #test2 @time begin for i=1:1000_0000 mm(10)(10,10) end end # 0.003385 seconds test2 is faster 30 times than test1. But in my view, test2 gene…

What is happening? Why these simple codes slow down Julia 30 times?

I suspect that you will see different timings if you put your tests inside functions or, if you stay in the global scope, use const gg = mm(10).
