we are using Wordpress 4.4.2 and the Wordpress Media Library for media management. We have noticed that as media (images, not videos or audio) number increases, the upload process takes too long...and the time it takes is about the same for both ie 50 kB and 6 MB images! It is not a network problem, this has been verified. Does Wordpress Media Library use an indexing method that slows the process down when the image number is big? Can we change the media upload directory so as to have an empty one at intervals?
Thank you in advance
