Who would have guessed? 

Who would have guessed?   Running a single thread task on two different 2700x cpus with different MBs.

Both system's CPU time vs. wall clock processing time shows the CPU to be in the ballpark of 10 seconds less than the wallclock time.

Windows 10 is averaging just under 2 hours per CPU task.

Ubuntu 20 is averaging about 90 minutes.

I have just switched both to 8 CPU tasks.

I believe the Universe at Home Linux effect has carried over to E@H Gamma-Ray CPU tasks... 

The gpu's processing speeds seem to be pretty consistent across either Linux or Windows.

I wonder if I can get a 1/3 drop in time on GW tasks?

On my 3950x box the highest priority has been processing Gravity Wave cpu tasks and then chasing the highest E@H RAC I can manage using gpus.  GW cpu tasks are running 4-5 hours for 6-8 tasks depending on the mix/amount of WCG tasks I run.

Since I have now demonstrated the ability to reliably generate an Ubuntu/Amd gpu setup across multiple MB's/cpu brands maybe it is time to revisit GW cpu tasks under Ubuntu.  This assumes stable hardware something I haven't been able to do with my Mining rig. Hmmmm.....

You've not really discovered

You've not really discovered something "new" Tom.

Linux has always been generally regarded as more "efficient" compared to Windows.

Better code optimization in the libraries compared to Windows DLL's and also a lot less unnecessary background processes running compared to Windows.

At 8 tasks per 2700x

Win10 seems to be averaging 3 hours and 19 minutes

Ubuntu seems to be averaging 2 hours and 41 minutes.

Switched to 4 tasks.

So my most important question is does it make a significant difference on GPU production?

My Mining rigs have been my least stable platforms.  And it has been very helpful to have the Windows-based tools for attempting to track down the problem(s).  So does using Linux give my GPUs a 10% processing boost or what?

Assuming I have a stable mining rig I may have to literally test that out.  I need to determine if I can run 5 GPUs reliably under Win10 like I previously did with the 2700x/X470 rig and a 1 to 4 expansion card.  I am running a different cpu (Amd 3900x), motherboard (x570) and a 1 to 8 expansion card right now.

that will vary project to project. i know its a 10-15% performance boost on GPUGRID on Linux vs Windows. not sure about here.

Well, apparently the LInux gpu drivers and two Rx 5600 xt's don't get along.  Back to Windows 10 after an exhausting 2-3 days of trying to get something/anything to work.
