Edge Canary limited disk usage capability on YouTube video upload
Microsoft Edge Canary latest ver. Version 75.0.133.0 (Official build) canary (64-bit).
so I was trying to upload a 40 GB video file to YouTube but due to a network error it got halted. as you know YouTube lets you resume your video upload if you choose the same file to reupload within the next few days. but before it resumes, YouTube needs to check the file first, so it needs to read the whole file in order to know where it needs to resume the upload from. so at first my 40GB file was on my hard disk and in task manager it showed that Edge canary's disk usage is 50 MB/s. then i decided to copy the file to my SSD drive, (C:\) but again i saw that Edge canary is only using 50 MB/s disk usage even though it's accessing the file on an M.2 super fast SSD with read/write speeds of more than 1000 MB/s each.
- looks like the limit only applies to YouTube when it tells the browser to check the video file so it can know where it should restart the upload from. i can't test the same thing on the preinstalled Edge since it's a painful process but i did test both of them by drag and dropping the video file on the browser and then selecting "save video file" so it started download it (actually copying the file from one drive to another) and the speed went over 300 MB/s (Megabyte not megabit)

HotCakeX Do you see different results with the old Edge (Spartan) or with Chrome?
Chrome's sandbox architecture may impact disk read speeds for local files, although I'd be surprised to learn that the impact is more than a few percent.Are you relying exclusively on the "Disk Usage" column in Task Manager for your analysis?
- By chrome you mean the chromium open source engine right? not the actual google chrome browser cuz this is actually Microsoft Edge.
anyways, i don't understand what you mean by your second paragraph. my SSD is capable of more than 1000 MB/s read speed (actual rate is 2000/1000 for read/write speeds) so there is something wrong that the new Edge is only using 50 MB/s. it is also an issue when we are downloading a file and Edge won't be able to download it faster than 50 MB/s.
Yes, unless you think Windows task manager is unreliable ?- Eric_LawrenceBoth the new Edge and Google Chrome are built atop the same Chromium architecture. I'm curious whether you see different results
I can't speak to the accuracy of the task manager's throughput column; it does appear to do some smoothing, for instance.
In a quick test here, I see downloads writing to disk at ~180mb/sec, which is roughly the peak write speed of this drive. Also, keep in mind that your system's antivirus scanners are likely scanning the data as it's downloaded to disk.
