transfer speed

[Enquiries]

transfer speeds became INCREDIBLY slow after upgrading DSM from 6 to 7. been using the unit since 2020 with absolutely no problems outside of not being able to access the DSM interface.

It sounds like your transfer speeds took a significant hit after upgrading your DSM from version 6 to 7. Here's what you can do to troubleshoot and hopefully resolve the issue:

1. Check Network Configuration
Network Settings: Ensure your network settings remained intact after the upgrade. Double-check that you're using the same network interface and settings (like Jumbo Frames) as before.
Cables & Connections: Verify that all Ethernet cables are securely connected and that they are still in good condition. Sometimes, a loose or degraded cable can cause speed issues.
2. Review DSM 7 Settings
Resource Monitor: Open DSM’s Resource Monitor to see if there are any processes consuming excessive resources, which could slow down transfers.
SMB Settings: If you use SMB for file transfers, make sure the SMB protocol settings haven’t changed. Try adjusting the SMB version (e.g., set it to SMB 3) to see if it improves speeds.
3. Re-index or Rebuild
Re-index Shared Folders: Sometimes after an upgrade, the NAS might need to re-index or rebuild databases related to shared folders. Check if there’s any ongoing indexing process and let it complete.
4. Check for DSM 7 Updates
Firmware Updates: DSM 7 is still being refined, so make sure you’re running the latest version. Synology might have released patches addressing performance issues.
5. Test with Direct Connection
Direct Connection: Temporarily connect your NAS directly to your computer with an Ethernet cable and test the transfer speeds. This can help isolate whether the issue is with the NAS or something in your network.
6. Consider Downgrading
Roll Back to DSM 6: If the problem persists and none of the above solutions work, you might consider rolling back to DSM 6. While not ideal, it could restore your previous performance levels.
