I'm not sure of the etiquette, but I'm cross-posting this from stackoverflow as it seems like quite a significant issue...
As an example: x = rand(10,10,100,4,4,1000) #Dummy array tic() r = squeeze(mean(x[:,:,1:80,:,:,56:800],(1,2,3,4,5)),(1,2,3,4,5)) toc() Julia 0.5.0 -> elapsed time: 176.357068283 seconds Julia 0.4.7 -> elapsed time: 1.19991952 seconds I know this isn't really good practice, and I'm looking into using `view` but it's quite a bit performance decrease, so I thought I'd raise it. http://stackoverflow.com/questions/40351485/why-is-indexing-a-large-matrix-170x-slower-slower-in-julia-0-5-0-than-0-4-7
