Performance on i5 better then on latest i9

See original GitHub issue

I have very basic test and very strange results.

console.time("ROTATE-RESIZE")
sharp('./photo.JPG')
  .rotate(90)
  .resize(200)
  .toBuffer()
    .then(()=> {
      console.timeEnd("ROTATE-RESIZE")
    })

On Macbook Pro Mojave ( Core i5-7267U, 8RAM, Iris VGA) execution time is ~93ms While on Desktop Ubuntu 18.4 (Core i9-7944X, 16Ram , M2 SSD, Geforce 1050) execution time is ~121ms

I bought this monster PC to speed up resizing, but in reality I got 20% performance decrease. Do you have any explanation ?

Thank you.

False alarm. One file processing make no sense. Once I run it on 590 different files, each applied unique set of modifications( scale, rotate, combine, extend, extract) - the result on Ubuntu machine was 4.1 times faster. ( 6.81min vs 1.66min)

More than happy.

Thank you for assistance and the package itself. Do you have donations wallet for “Sharp” ?
