I have a a Photos library which is around 335GB.
I deleted 23k photos from it (leaving only the photos from 2015-2016) and the size is almost the same: now the size is 330GB.
After deleting them I also emptied the Recently Deleted album.
How to solve this? How to speed up the deletion process?
Using the latest Photos and macOS versions.
When you choose to export from Photo (File>Export), choose TIFF, 16-bit and you should get a full quality, uncompressed, but edited image out of Photo. This is what the settings in the export dialog box will look like:
The reason you haven't found the folder with the edits are that image editing programs such as Photo or Adobe Lightroom perform non-destructive edits as an instruction set that sits in a database that references the original image. Basically your edits just create a recipe that the software then can use to create an output file. If you choose to print, it will give the instructions on how to render the edited image to the printer. The only time you will get an edited file is if you export to a file format such as JPEG or TIFF.
TIFF gives you an uncompressed file, and by choosing 16 bits, the software is actually interpolating to add pixels to your photos as most digital camera sensors produce a 12 or 14 bit image. There isn't much of a point for more, as the human eye has a hard time distinguishing the available gradations of a 16-bit dynamic range.
JPEG is a Lossy compression format, but for even a 5K iMac, if you go for the highest quality, largest file size, you will likely not be able to see a difference between the TIFF and the JPEG version of the file, and you will have a file that is probably 80% smaller, depending on the subject matter.
You also have the option of exporting the Unedited originals (Raw files) using this option as well. There is an option to export IPTC data as an XMP sidecar file.
A late thought… which might depend on how much 'organisation' you'd be willing to lose.
If you right-click the Photos Library & select Show Package Contents, then inside there, the Masters folder contains just the photos. All of them, but nothing else.
Everything else inside the library package is 'organisation'.
You could test creating an entire new Library by

Photos does not reclaim disk spaces immediately after you empty the Recently Deleted folder. Keep Photos opened and allow it to reclaim the disk space. It does take some time. I believe that they are the image caches, thumbnails, indices for searching and all other metadata files being cleaned up in the background. There are a lot of layers to how the photos are stored, so there is a lot of different files to clean up. I'd connect to the ac power and just don't let your disk or computer go to sleep.
