Hello Marcus,
Thank for looking into this... The computer is a NUC 13 Extream (i9).
As for the ethernet interfase I am using the 10 Gigabit Ethernet port
on the x310 and the NUC support 10 GBe.
If you think of anything else... please reach-out.
Thank you,
AJ
You can use the "benchmark_rate" tool to see what the range of sample
rates are that your compute can support.
This doesn't do any processing at all, just moves samples into and out
of the radio.
An i9, assuming it's running in "performance" (or perhaps "OnDemand")
should be doing just fine at considerably more
than 2.5Msps.
Something I forgot to clarify. What OS? If Linux, are you running it
in a VM, or on "bare metal"??

Hello Team,
I am operating a set of X310 in communication link, and I seem to
be encountering data under and overflow problems very regular
while operating at 2.5Msps… my target is at least 100MSps. Are
there any suggestions you can offer? My MCR is 200MHz.
Thank you, look forward to hearing from you.
If you're getting under/over-runs at 2.5Msps, then either your
computer is *WOEFULLY* inadequate or you're doing
WAY more processing per sample than perhaps you should be.
I run a dual-polarization radiometer based on an X310 and it can
stream 2x20Msps for hours at a time.

Also, is your Ethernet interface a "real" Ethernet interface or
1GBit-over-USB? Some of those have notoriously
poor performance.
