An RDMA perftest tool is open source now.

A lightweight, extremely short-interval RDMA performance testing tool.

What you need before using this tool

You may need an RDMA Network interface card, with two different virtual machines, or you can use two different physical machines, each one has an RDMA NIC.
We used standard IB verbs, you can use OFED driver to enable your RDMA NIC.
If you don’t have any RDMA physical devices, you can also try Soft-RDMA.

Brief introduction

This test tool provides performance tests for various RDMA operations. Users can customize the use of any port and gid of any device, and can specify precise test cycles (microsecond level). Users can also specify the batch size and message size of the test.
