Hmmm.
I think this may be inline with some of the information @wendell has shared in some of his testing over the years.
(151) Record Breaker: Toward 20 million i/ops on the desktop with Threadripper Pro - YouTube
When he is pushing PCIe Gen4 on ThreadRipper, I think it’s pretty obvious that both in terms of memory and CPU, that is really what’s holding us back.
I’m going to order this:
Linkreal PCIe 3.0 X16 to Quad M.2 NVMe SSD Swtich Adapter Card for Servers LRNV9547L 4I|Add On Cards| - AliExpress
To see if I can squeeze some more performance out.
These are the two differant PLX chips
I don’t know if an improvement in PCI-E alone will assist, but it’s not going to hurt (beyond my wallet) to try… I will update this once I receive them in a few weeks, obviosly have to wait for shipping from China
