It's probably not the memory speed, so much as the next generation AMD processor (7950 vs our "normal" 5940s) plus those CT4000s (those are the super-fast PCI 5 gen nvmes). This was also run using Ubuntu 23.10, which has higher performance mitigations of CPU vulnerabilities.
Hummm, good point about ubuntu 23, will give it a try! Here in NZ, the 990 PROs (samsung) are more cost effective, price/capacity wise, but lets see (waiting for the gen5 to stabilize the prices here, and then making the choice, for a 4 to 5 NVMe ZFS setup. My aim is to run everything HIVE+HAF+HE on the NVMes and then snapshot to my disk array, for regular "backup" solution.
For the most part, our systems use 980s and a couple of 990s. We got this one system a couple of weeks ago specifically when we needed to run replays as fast as possible.
On the Ubuntu 23.X, had to add #include <cstdint> to two header files. But so far, looks interestingly different.
We build/run dockers in ubuntu 22 still. You only need 23 for the "host" that runs the dockers, so there's no need to compile on Ubuntu 23 if you don't want to.
Curious about how fast can local replays go on the 7950X with the T700s? I am doing some tests myself too (different gear) and will share them once I have compiled enough conclusions.
