pts/memtier-benchmark
=====================

memtier_benchmark measuring Redis/Memcached throughput and latency under configurable load.

Benchmark Profile
-----------------

- Type: Macro
- Kernel subsystem: Networking, TCP, scheduler, memory management
- Coverage: Inferred from database-client throughput and latency
- Topology: Single role: executer

Overview
--------

memtier_benchmark drives configurable read/write workloads against
Redis or Memcached servers to measure throughput (ops/sec) and latency
at various client concurrencies. Sensitive to network stack and lock
contention changes.

Fastpath Parameters

Name            Description
==============  ===================================================================================
test-profile    PTS test profile string identifying the memtier variant.
preset-options  PTS preset option indices controlling protocol, key/value sizes, and client counts.
rc-regex        Regex to extract result class name components from raw output.
rc-template     Template to format the result class name from regex capture groups.
==============  ===================================================================================

Result Classes
--------------

Result class names encode protocol, operation ratio, and client count.
