Re: [Discuss-gnuradio] [UHD] Announcing 3.14.0.0 Release Candidate 1

Hi Andre,

The one example I can give at this time is limited and semi-anecdotal as
I've only tested it on a single machine.

With an i7-4790k / Intel x520-DA2 and N310, to stream at full duplex, over
two channels at 125 MS/s, the lowest I can run my CPU clock freq at without
flow control errors is 3.8 GHz using benchmark_rate and the native
networking stack. Using DPDK I can run 2x2 @ 125 MS/s with my CPU freq
locked at 1.5 GHz with no flow control errors.

Regards,
Nate Temple

Hey guys,

any idea or numbers on the performance improvement using DPDK, e.g. CPU
usage during rx/tx streaming, when compared to the legacy approach?
Would be great to get a feeling for the achievable gains.

Thanks
Andre

a DPDK-based transport, and several other features and bug fixes.  This
release includes all bug fixes and enhancements in the 3.13.0.1, 3.13.0.2,
and 3.13.1.0 maintenance releases.
