Issue:
After updating to TOS 5.1.X from TOS 5.0.X, SMB speeds have dropped from usual 100 mb/s and now average around 20mb/s, but have seen consistent speeds as low as 5 mb/s.



Hooking monitor up to TNAS while it's running, entire screen is a log of Remedies mentioned in the 5.1.67 update post say to either change the boot disk order or to disable hpetm however I can't do either of these in the BIOS, the option is simply not there.

Forgot to mention, I upgraded from 5.0 to 5.1, encountered slow SMB speeds, then did a reset and a clean install to 5.1 and issue persists.

Do you have scheduled "power off/power on" functions entered in the control panel? We have been down this path before.

Shoot, I do have that.

Suggest you remove all the entries (disabling is not sufficient) and check SMB again. Please report back for my benefit if noone else's

@gremlin - disabling the schedule seemed to fix SMB, but I'll delete them next and see. Plugging the TNAS into a monitor, I can see the hpet: lost waterfall stopped soon as I turned the schedules off.

Thanks, that (disabling only) seems like a slight change from previously.

I did end up deleting the power schedules as well, just to be safe / I don't need them so why keep them.

It's probably a safe assumption that scheduling events, like enabling/disabling an app, would also cause hpet to turn on. I didn't have any of those but will keep in mind probably best not to set any.

I run customised scheduled event every day (find and delete files) and it has no effect. It only seems to be the power on/off schedule that has been an issue. (so far!)
