The deployment of Windows 11 22H2 turns out to be far more traumatic than Microsoft would like. There aren’t a few bugs we’re covering these weeks, and we’ve even seen how the misprint is causing Redmond to roll back and pause the update on some devices.
The fact is, as I said, is not the only bug that affects this version. We are aware of an issue when copying large files that results in up to 40% system speed loss when copying files remotely.
Windows 11 22H2 and File Copy Error
About this 40% speed loss is the figure officially recognized by Microsoft. The reality is that in many cases we see how it affects 100%, sometimes leaving SSD locked until a full system restart. It is virtually impossible for the system to recover at this point, as there is no option to open or the task manager to kill the process.
User ivicask, a regular and respected member of Microsoft’s tech community, had this to say to Ned Pyle, a Microsoft insider who acknowledged the core bug:
I would just like to correct the 40% slower speed statement than Ned stated, I see more than 100% difference in configurations like the difference in 10Gb NICs (5Gb/s vs 2Gb/s), or in SMB configurations multi-channel with multiple gigabit NICs.
For his part, Pyle has confirmed ivicask’s thesis, but not completely and without giving figures for the moment.
I can’t share too many details yet, but we know exactly where the kernel is slowing down, nothing to do with SMB or compression.
It’s time to wait because there is no solution for this problem at the moment. We will keep you informed in case there is any news on this.
