I noticed Plex Media Scanner was using nearly all my CPU resources, causing my computer to slow down. It turned out to be running multiple scans at once. Reducing the number of scans and updating the software helped a lot.
If Plex Media Scanner is using too much CPU, it might be scanning or updating a lot of media files. Try limiting the number of scans, updating Plex, or running scans during off-hours to reduce CPU usage.
Stay tuned with us as we dive into the topic of “Plex Media Scanner High CPU.” We’ll discuss why this happens, how it affects your system, and ways you can reduce CPU usage easily.
What Is Plex Media Scanner?
Plex Media Scanner is a tool within the Plex Media Server that scans your media library to organize and gather information about your files. It looks for details like titles, descriptions, artwork, and more to make your media easy to browse and search.
The scanner helps Plex display your media neat and organized, ensuring everything in your library is updated and ready for streaming.
Why Does Plex Media Scanner Use High CPU?
Plex Media Scanner can use a high CPU because it works intensively to analyze and organize large media libraries. When it scans, it processes a lot of data, including checking file formats, metadata, and artwork.
If you have a large collection of complex files, the scanner needs more resources, causing the CPU to work harder. This is why sometimes you might notice your computer slowing down during the scan.

When Does Plex Media Scanner Run?
Plex Media Scanner usually runs when new media is added to your library or if you manually start a scan. It can also run periodically in the background to ensure your media is updated and correctly organized. You can adjust when it runs through Plex settings, either scheduling it or having it scan automatically when changes are detected in your media folders.
How Can High CPU Usage Affect My System?
Slower Performance:
High CPU usage can make your system run slower, as it uses a lot of processing power. Tasks like browsing or using apps may feel sluggish.
Overheating:
Continuous high CPU usage can cause your computer to overheat, which might affect its overall performance and lifespan.
Lag in Other Programs:
When Plex uses too much CPU, other programs may struggle to function properly, leading to delays or unresponsiveness.
Fan Noise:
High CPU usage often causes your cooling fan to run at full speed, making your computer noisier than usual.
Battery Drain (Laptops):
On laptops, high CPU usage can drain the battery faster, reducing the time you can use the device without charging.
How Can I Reduce CPU Usage By Plex Media Scanner?
Lower Scan Frequency:
In Plex settings, you can reduce how often the scanner runs by scheduling scans at specific times or less frequently.
Run Scans at Low Priority:
You can set Plex Media Scanner to run at a lower priority, which allows it to use less CPU and lets other programs work smoothly.
Limit Background Scanning:
Turn off continuous background scanning and only run manual scans when needed. This reduces how often Plex uses your CPU.
Optimize Library:
Remove unnecessary files or organize your library better. A smaller or cleaner library will take less CPU to scan.
Use Faster Hardware:
If possible, upgrade your CPU or switch to a device with more processing power, which can handle scanning tasks more efficiently.
Does Disabling Plex Media Scanner Solve High CPU Issues?
Disabling the Plex Media Scanner will stop it from using CPU resources, but it also means Plex won’t update or organize your media files. This can lead to outdated metadata and a disorganized library. If high CPU usage is a big problem, disabling the scanner can help, but it might affect how well your media is managed.
Can Updating Plex Help With High CPU Usage?
Yes, updating Plex can help with high CPU usage. New updates often include performance improvements and bug fixes that can reduce CPU load. Keeping Plex up-to-date ensures you benefit from the latest optimizations and fixes, which can help your system run more efficiently.
Are There Any Alternative Ways To Fix High CPU Usage?
Limit Scanning Frequency:
Reduce how often Plex Media Scanner runs. Instead of scanning frequently, set it to run less often. This will give your CPU more time to rest and handle other tasks without being overloaded by constant scanning.
Update Plex Software:
Make sure you have the latest version of Plex. Updates often include performance improvements and bug fixes that can help reduce CPU usage. Keeping Plex up-to-date ensures you get the best performance and stability.
Use Hardware Acceleration:
Enable hardware acceleration in Plex settings if your hardware supports it. This feature offloads some processing tasks to your GPU, which can help reduce the load on your CPU and improve overall performance.
Optimize Media Files:
Ensure your media files are well-organized and properly encoded. Well-organized files are quicker for Plex to scan, and properly encoded files can reduce the amount of processing needed, which helps lower CPU usage.
Adjust Transcoding Settings:
Lower the quality settings for transcoding in Plex. Higher-quality settings use more CPU power. By setting transcoding to a lower quality, you can decrease the CPU load and make the system run more smoothly.

If the problem remains, consider upgrading your hardware for better performance. Finally, consult Plex support or user forums for additional troubleshooting advice tailored to your specific setup.
What Does Plex Media Scanner Do?
Plex Media Scanner organizes and indexes your media files. It reads the information from your media, updates the library, and creates metadata for better browsing. This process helps Plex display your movies, shows, and music properly so you can easily find and play them. It makes sure your media is correctly sorted and ready for streaming.
What Is Run Scanner Tasks At A Lower Priority Plex?
“Run Scanner Tasks At A Lower Priority” means setting Plex to use less CPU power for scanning tasks. By lowering the priority, Plex lets other important tasks on your computer run more smoothly. This can help prevent Plex from using too much of your CPU, improving overall system performance while still keeping your media library updated.
What CPU Cores Do I Need For Plex?
For basic Plex use, a quad-core CPU (4 cores) is usually enough. However, if you plan to stream or transcode multiple media files at once, more cores are better. A CPU with at least 4 to 6 cores is recommended for smooth performance, especially for handling high-definition content and multiple streams simultaneously.
What Is The Minimum CPU For Plex 4k Transcoding?
For Plex 4K transcoding, you need a powerful CPU. A minimum of a recent quad-core processor, like an Intel i5 or AMD Ryzen 5, is required. A faster CPU with more cores, such as an Intel i7 or Ryzen 7, is recommended for better performance. 4K transcoding demands a lot of processing power to handle high-resolution media smoothly.
Does Plex Transcode Use CPU Or GPU?
Plex transcoding primarily uses the CPU to convert media files into a compatible format for streaming. However, if your hardware supports it, Plex can use the GPU (Graphics Processing Unit) to speed up this process. Using a GPU for transcoding can reduce the load on your CPU and improve overall performance, especially for high-definition content.
What Is The Best CPU For NAS And Plex?
The best CPU for a NAS (Network Attached Storage) running Plex is one that offers a good balance of performance and efficiency. An Intel Core i5 or AMD Ryzen 5 is often a good choice.
For more demanding tasks or multiple streams, consider a more powerful processor like an Intel Core i7 or AMD Ryzen 7. These CPUs handle media streaming and file management effectively.
