About this tag
Discussions tagged with i/o performance on WindowsForum.com cover real-world tuning and troubleshooting of storage and thread behavior in Windows. One thread examines Windows 11's Dev Drive, a ReFS-formatted volume with Defender performance mode that improves build times, git operations, and file copies for developers. Another thread addresses a Windows 7 issue where a single thread set to Real Time priority and busy-waiting for I/O causes the entire OS to freeze, a problem not seen in Windows XP. These posts reflect common concerns around balancing responsiveness and system stability when optimizing I/O performance on Windows.
