"\nThe --measure_* options aid in taking latency measurements of the\nmemcached server without incurring significant client-side queuing\ndelay. --measure_connections allows the master to override the\n--connections option. --measure_depth allows the master to operate as\nan \"open-loop\" client while other agents continue as a regular\nclosed-loop clients. --measure_qps lets you modulate the QPS the\nmaster queries at independent of other clients. This theoretically\nnormalizes the baseline queuing delay you expect to see across a wide\nrange of --qps values.\n\nPredefined profiles to approximate some use cases:\n1. memcached for web serving benchmark : p95, 20ms, FB key/value/IA, >4000\nconnections to the device under test.\n2. memcached for applications backends : p99, 10ms, 32B key , 1000B value,\nuniform IA, >1000 connections\n3. memcached for low latency (e.g. stock trading): p99.9, 32B key, 200B value,\nuniform IA, QPS rate set to 100000 \n4. P99.9, 1 msec. Key size = 32 bytes; value size has uniform distribution from\n100 bytes to 1k; \n\nSome options take a 'distribution' as an argument.\nDistributions are specified by <distribution>[:<param1>[,...]].\nParameters are not required.
