How performance craters when defective power supplies, power throttling and BIOS settings intersect!

Attempting to share a PDF...

OK there's a 1024KB file size limit! WHAT? come on guys... raise that please!

Please note that the results documented within the PDF may not only be caused by a defective PSU!

The PSU power capping / throttling settings, which multiple vendors provide and support, could be impacting system performance across the board and everyone not realize it. The overall impact is very real.

Cheers,

Hello Greg,

Are you referring to below KB from VMware?

Yes and No. It is related and in the ballpark but not exactly that. The PDF shares our real observed impacts to the workloads. In this case the workload was Foglight itself and the impacts so severe that Foglight became virtually unusable.

Can you please email me the PDF so that I can get it uploaded here.

Hi Greg,

Seems we have the same restriction. We have contacted our people to get this fixed

Hi Lee and Prasad: Any progress on posting the PDF? I was surprised you guys were under the same limit restrictions. Thanks.

Hi Greg,

Chris is working on it, let me check and get back to you.

I compressed the original file little bit so we post here and share with community on your behalf.

Lee, Super! Thank You for finding a way to compress / post! The graphs took the brunt of the compression but they remain readable.

BTW, I am waiting on one more set of feedback for the 2nd article. Targeting next week.

Any questions, post here and I'll try to promptly respond.

All, have a great weekend!
