Zorluk: OrtaTroubleshooting Windows Performance and Application Crashes

A systems administrator notices severe system responsiveness degradation on a Windows 11 workstation during high-resolution media export operations. Performance Monitor reveals that while CPU utilization remains under 35%, the PhysicalDisk Avg. Disk Queue Length metric consistently exceeds 6, causing the application to hang. Which TWO actions should the technician take to resolve this disk subsystem bottleneck?

  1. Relocate the application's temporary scratch directory to a separate physical solid-state drive.Cevap
  2. Configure Windows virtual memory settings to allocate a secondary paging file on an alternate physical disk.Cevap
  3. C
    Adjust the application's process priority to Realtime in Task Manager to prioritize disk processing.
  4. D
    Execute `sfc /scannow` from an elevated Command Prompt to rebuild the storage controller driver stack.

Cevap

The technician should relocate the application's temporary scratch directory to a separate physical drive and configure virtual memory to place a paging file on an alternate physical disk.
High Avg. Disk Queue Length metrics indicate that disk requests are backing up because the storage device cannot process I/O operations fast enough. Distributing heavy I/O tasks—such as application scratch files and virtual memory paging—onto separate physical drives relieves contention on the main disk and lowers queue depth.

Adım Adım Çözüm

1
Analyze Performance Monitor metrics to identify the resource bottleneck.
Low CPU usage combined with a high Avg. Disk Queue Length (>2 per disk mechanism) indicates a disk I/O bottleneck rather than a processor constraint.
Accurately identifying the bottleneck prevents ineffective troubleshooting steps like altering CPU process priority.
2
Isolate high-volume disk I/O tasks from the OS system drive.
Moving scratch/render directories to another physical disk distributes read/write traffic across separate controllers and storage media.
This reduces contention on the primary storage drive hosting the OS and active applications.
3
Optimize virtual memory placement across physical drives.
Splitting or moving the Windows paging file to a secondary physical disk allows virtual memory reads/writes to occur simultaneously without competing with OS file operations.
Distributing pagefile traffic mitigates disk queue bottlenecks during memory-intensive operations.

Anahtar Kavram

Identifying disk I/O bottlenecks via Disk Queue Length metrics and resolving storage contention through drive separation and paging file configuration.
