Introduction

sockperf_v1 is based on Voltaire's udp_lat and only supports UDP traffic (both UC and MC).

sockperf_v2 adds TCP support (and some complexity in the code)

Details

sockperf_v1 is based on udp_lat and adds to it:

  • latency under load mode
  • playback mode
  • discrete measurements at packet level (based on RDTSC) that allows providing better statistics (like histogram).
  • additional switches and new options
  • major design changes for making the code easier for maintenance, while still keeping good performance and even improving it a bit.

sockperf_v2 is based on sockperf_v1 and adds to it TCP support (and few more options). It introduces more complexity in the code, but still provide the good performance.

In addition, sockperf_v1 was developed internally in Voltaire (acquired by Mellanox). While sockperf_v2 was mainly developed by 3rd party contractor. Both versions are maintained by Mellanox.
