Important Notes

• This update is only for TOS 5.1.24 or later versions. If your TOS version does not meet the requirements, please update to TOS 5 by reinstalling TOS.

• There is an error in the encryption mechanism of encrypted folders created on TOS 5.1.37, which prevents them from being decrypted in later versions. Therefore, if you are using TOS 5.1.37, before updating TOS, please back up the data in the encrypted shared folder, and then delete the encrypted folder. (Only need to deal with the encrypted shared folder created in TOS 5.1.37, other encrypted Shared folders are not affected by this)

• The kernel of TOS 5.1 has been updated to 5.15. Since the Linux kernel has removed the Intel Celeron J1800/J1900 GPU drivers from 5.15, the models of this platform no longer support GPU hardware video acceleration. If you are a user of this series of models and need to use GPU hardware video acceleration, do not update TOS 5.1! Models involved: F2-220/F2-420/F4-220/F4-420/F5-420

• Under normal circumstances, the system update will not affect the data in your hard drives, but for your data safety, it is strongly recommended that you back up your data before the update!

Not encouraging. I think I'll wait before I update (and maybe a clean install).

I did a clean install with version 5.1.41 and made no changes to the start times. Then I installed version 5.1.67 and changed the start and stop times. The SMB transfer rate dropped again.

For 221 series, the hpet option is set as enabled by default in BIOS, As a result, a large number of invalid requests are generated, which occupy system resources, and the speed of SMB is affected. We have stopped requesting hpet in the latest TOS version, and we have verified that the countermeasure is effective. As for your case, we need further verification.

You can try to change the hpet option to disable in BIOS.
