Daniel Lockyer eef85bba90 Disabled Sharp's internal cache to improve memory usage ... refs https://sharp.pixelplumbing.com/api-utility#cache - Sharp has a 50MB cache by default, used within libvips, to increase the performance of transforming images - this isn't relevant to us because we should never be optimizing the same image as we check if the optimized image already exists - I presume there is also some extra overhead of using the cache because the memory doesn't seem to grow by 50MB - the memory usage comparison in Ghost is pretty drastic - uploading 10 images in serial w/ jemalloc: - with cache (default) = peak of 480MB, settles down to 330MB - disabling cache = peak of 270MB, settles down to 161MB - this commit disables the cache - also adds stubbing for the function in tests		2021-11-05 11:59:39 +00:00
