pedroperezmsft/qperf repository overview

⁠SUMMARY

qperf is a Linux command that measures bandwidth and latency between two nodes. It can work over TCP/IP as well as the RDMA transports. ... One may then run qperf on a client node to obtain measurements such as bandwidth, latency and cpu utilization

⁠USAGE

⁠Server side

docker run -dti -p 4000:4000 -p 4001:4001 pedroperezmsft/qperf -lp 4000

⁠Client side

⁠tcp latency

docker run -ti --rm pedroperezmsft/qperf 10.1.4.5 -lp 4000 -ip 4001 tcp_lat

⁠tcp bandwidth

docker run -ti --rm pedroperezmsft/qperf 10.1.4.5 -lp 4000 -ip 4001 tcp_bw

⁠tcp latency + bandwidth + system conf

docker run -ti --rm pedroperezmsft/qperf 10.1.4.5 -lp 4000 -ip 4001 tcp_bw tcp_lat conf

⁠Results

tcp_bw:
    bw  =  126 MB/sec
tcp_lat:
    latency  =  188 us
