Eagle showed "bad library storage performance", how do I fix it?
If Eagle shows the notification "Bad Library Storage performance", this could mean the device where you store the library has insufficient read speed, so Eagle is unable to display images at the utmost speed.
Should you encounter the situation, please try the following troubleshooting steps:
Before trying the solution below, you could try download Eagle's latest version , the issue you've encountered could've been fixed in the new version.
- Check if you're using a third party app to access an NTFS formatted disk
Based on our dev teams test, the random read performance will be hindered significantly whether you're using Tuxera NTFS or Paragon NTFS apps; If possible, we still recommend you to store data on a disk with compatible formats. (APFS / HFS+)
- Check if the macOS version is Ventura 13.0 (2022/11/01 updated)
This is a known system bug from the macOS Ventura 13.0 version, there have been many similar reports on Mac forums. Currently, not only Apple's native hard drive format (APFS, HFS+ ) is affected, but other formats (exFAT, NTFS, FAT32) ‘s performance is also affected. Eagle dev team has tested internally, the reading speed may be decreased up to 10 times the normal performance. The current solutions are:
- Wait for a new update from macOS
- Downgrade to macOS 12.6
If you backed up your device before upgrading the system using Apple's Time Machine, you can temporarily return to the previous version, please refer to this article.
- Change your hard disk format
If you do not have the requirements to switch between Windows / macOS systems, changing the hard drive format might be a better solution. (As using the hard drive formats that align with the native macOS system, the performance will improve significantly)
- Check if your device is plugged in a USB 3.0 port
If you use external storage, the reason being to this could be the storage is plugged in a USB 2.0 port, or there is a problem on the USB hub you use, resulting in low performances. Please switch ports or leave your hubs to see if the performance returns to normal.
- Check the disk performance
Check the disk performance with software like Blackmagic Disk Speed Test (MacOS) or CrystalDiskMark (Windows). The recommended read/write speed is no lower than 50MB/s
- Upgrade to faster devices
If possible, consider upgrading your hardware to allow Eagle to run in the best performance. The recommended read/write speed is no lower than 50MB/s
To secure a best Eagle experience, we recommend you to store the library on the storage with better performance.
