I can't say I have experienced any slowness today but I was not around at the time of your message.

Admin have confirmed several times that sending a ticket to 'contact us' with detailed information (time/timezone of when the issue(s) occurred, type of error, device/browser information, screenshots/video if possible) is the best way for them to trace and identify performance problems.

It may be a good idea to check your internet connectivity as well, and perhaps try using a different WiFi connection if you are able to, activating a mobile hotspot or using mobile data. Performing an internet speed test and sending the results in your ticket to support may help them identify the problem as well.

Found the problem. Locking.
