AutoGrad slower in Julia5 compared to Julia4

[denizyuret]

Following is an example from Knet test scripts. Julia4 is >2x faster both in the first run and in the second run of testall(). Anybody with more insight into Julia have any idea why?

using AutoGrad

function testall()
    for f in (sum, prod, maximum, minimum, sumabs, sumabs2)
        g = grad(f)
        for t in (Float32, Float64)
            for n in (1,(1,1),2,(2,1),(1,2),(2,2))
                d = g(rand(t,n))
            end
        end
    end
end

@time testall()
@time testall()
