Performance degradation is never a pretty sight, especially when it involves copying large files. Unfortunately, this is exactly what this latest issue in the newly released Windows 11 22H2 is doing.
Microsoft has officially confirmed this bug lives in the latest version of its operating system, which thankfully is not a problem in the initial release of Windows 11. Thus if you are still rocking the vanilla OS, you will not encounter this.
So, what’s exactly the issue, you ask?
Well, this post on the Tech Community forums has Ned Pyle, the Principal Program Manager in the Windows Server engineering group, sharing the details.
Users are warned about performance degradation when copying large files from a remote computer to a system running the latest version of Windows 11. Apparently, users who do this experience massive slowdowns.
The throughput is up to 40% lower due to the presence of this bug in the Windows 11 2022 Update.
Interestingly, the bug is not exclusive to SMB. That is to say, users might notice performance dips even when copying local files. SMB, of course, is the Server Message Block network file-sharing protocol that comes into play when moving files.
While Microsoft is busy investigating the issue and figuring out a fix, affected customers can, in the meantime, use robocopy or copy commands with the /j parameter to restore the lost performance.
Expect to hear more from the company on this bug.
