Piwigo Test Ended Negative

The main problem with such a test is that I can't point the finger at the problem, whether it's the latest version of Piwigo, or its extensions, or my web server, or again the PHP version. It was incredibly slow and I couldn't work with PDF, animated WebP and mp4 files. And before I waste my precious time trying to get it to work, I quit and wait for the next version. This damn PHP is really getting on my nerves. Better luck next time.
