Fair enough in one aspect but I wasn't interested in how optimised or not things are but more interested in a ballpark approximate indication of how things look so far

The fact that it boots wickedly fast is also an indication is it not?

VSI have stated they are constantly running automated tests, more than ever before apparently, these will have metrics associated, I highly doubt detailed performance data is not part of this capture and I suspect that they would also have actual workloads being pushed onto those test systems to thrash out issues that crop up over larger and longer running workloads

Data is being collected, ideas formed and inferences made, they are not running blind here, not at this later stage of the port

It's in EAK form already, shipping it to people to kick the tyres and what I indirectly hearing is that they could be doing so with zero idea of how it will perform? I find that rather hard to believe

VSI engineering is great but their marketing leaves a lot to be desired and I think a fair chunk of the success or failure of VMS in the future will be tied to marketing. History is littered with examples of the superior product failing against the more marketed. VMS has captive customers but only for so long

If there is any perform gains known about, no matter how rough, I think VSI would be smart to use this especially in places like this, as a form of indirect marketing/advertising teaser to VMS customers that the 6+ year wait is worth it

The converse to this would of course be if performance is bad or pathetic...
