I am wondering if PCIe or it's drivers may be a problem for low latency.
Having read a little about the standard, it would seem that the earliest
standards (v1) are better for low latency than later (v4) standards. The
improvements have been in throughput at the expense of latency. I wonder
if it is possible to have a PCIe slot set to a particular version of the
PCIe standard. Or to do so at the card end. As a distro assembly
volunteer, I can only test things with the HW I have, which is older (no
PCIe slots at all). What I have read about the RME PCIe products is that
they are native PCIe rather than bridged PCI to PCIe.
I wish I had the funding to test full time and buy a better representation
of the HW out there, but I don't.
