Our performance counter of the week is a key storage related metric - CMDs/Sec. This is part of our new effort to cover a a new performance counter every week - along with a little bit of other virtualization and cloud stuff as needed. We secretly hope to make you all esxtop performance experts.
This week on So Say SMEs, Kong and I discuss what the costop or %costop performance counter means and how you can use it to resolve performance issues on your vSphere / ESXi environment. You can view costop in esxtop on the main CPU screen that comes up by default.
This week in our So Say SMEs episode we have a quick discussion about the CPU Ready time performance counter in esxtop. This has been covered by some other great blogs and esxtop performance guides. Here we have a quick intro conversation and also talk about the Super Bowl - because we have to talk about the Super Bowl.
Kong and I have returned for a third season of So Say SMEs. We have a few changes for season 3, but we will continue to talk cloud and virtualization with some geek and sports talk too. In terms of changes - Kong has moved over to SolarWinds and we going to focus a bit more on performance when we get the chance.
My voice is still not 100% in this video, but that is a story for another day!
As Kong continues his job search we found a place that was hiring for this week's episode of So Say SMEs. Chuy's is of course the perfect place to discuss the new vSphere Flash Read Cache feature aka vFRC.
I decided to wear a vintage work shirt this week - from a company that no longer exists. Anybody remember Altiris?
In the benchmark world, the Transaction Processing Performance Council (aka TPC) has long been the owners of the premier performance benchmark. I'm referring to the TPC-C database performance benchmark where millions have been spent to prove performance excellence.
This means that the HP and VMware vSphere solution has the "Leadership" position for the TPC-VMS benchmark - as of right now.
What happens next will be interesting.
The first published result establishes the target for everybody else. Will there be a bunch of publications over the coming months? Each a little bit better. Or will it take some time for anybody to be able to surpass this initial publication?
It is also of course possible that nobody else will ever publish a TPC-VMS result. Sometimes new benchmarks just never get established. If this is the case, then vSphere would hold the number one position forever. But this isn't what we want.
Ideally the healthy competition of a benchmark fosters innovation, software and hardware improve, costs come down, and customers benefit.
