Guys,
Across computers and browsers, I have had PAINFULLY slow Goggle Drive Uploads for the past three months. It's like you have to pause, and wait 30 seconds for commands to execute. The same is true with right-clicking in Goggle Drive, or doing almost anything in Goggle Drive.
I am using Firefox and MS Edge. MS Edge is even worse. I also get a webpage yellow bar that says, "A Webpage is slowing down your browser, what would you like to do?" There are stop and wait options. If you do nothing the data will eventually download. Clearing History and Cache does nothing.
The most important thing to say, is that I have no speed problems at any other websites, or downloading or uploading to any other sites, or from any other sites. These remain fast. Furthermore, Goggle Search is great, Goggle Docs composing, saving, and editing is great. But on uploading data to Goggle Drive's server, it is slower than snails. Goggle Downloads can be slow at times, but not nearly as slow as Goggle Uploads.
