Icloud email is unusably slow on all devices including IOS

Here's a very boring video showing how it takes the web interface 40 seconds to delete an email in iCloud. Shameful.

Thank you for taking time to help me with my problem.

Unfortunately, since the problem exists on all front-end applications, including the native web application written by Apple, the suggestions are not helpful. 40 seconds to delete an email or reply to an email or send an email is ridiculous, and Apple should be ashamed.

Here is the evidence:

That is helpful, to a point. If it is not a general problem, then maybe Apple has it out for me? The rest of my web experience is acceptably fast. This slow issue happens on Safari, Chrome, and Firefox. It happens at work and at home. I feel like somehow Apple has me set to communicate to a server in Korea, or something. Any suggestions to help me debug this would be much appreciated.

Unfortunately, this is not limited to Macs. I am on a PC at the moment. Also, deleting email on my IOS 8 iPhone has timed out, and the emails I deleted have returned like zombies.

All,

Thank you again for your comments and the time you took to respond to my concerns.

I am happy to report that the issue has been fixed, unceremoniously, in the middle of the night, My icloud email performance is now equal to or better than gmail.

Unfortunately I have no information to add regarding what changed, what got fixed, or if (indeed) my behavior had anything to do with this. I can simply state that I made no changes on my end other than rebooting one of my computers. (Recall this happened on three computers (Mac, PC), and using Outlook as well as the web-based portal on three different web browsers.)

Thank you,

Bill
