Performance Measurement

This directory contains simple performance measurement utilities:

• inproc_lat.rb measures the latency of the inproc transport
• inproc_thru.rb measures the throughput of the inproc transport
• local_lat.rb and remote_lat.rb measure the latency of other transports
• test_latency.sh run all latency tests
• test_throughput.sh run all throuput tests
