McShredder

Shredder's Revenge is a great videogame. McShredder is a high speed workload emulation and benchmark tool for memcached. It is a descendent of mc-crusher

  • Lua scripting for easily emulating client workloads
  • Scales to many client connections
  • Mixing of workloads in a single test
  • Easy workload rate limiting
  • Multi-threading for scaling workloads
  • io_uring network loop

This is an early release of the tool, with an "early and often" mantra. See issues on github to track planned work or contribute.

Dependencies

Most dependencies are vendored within the source.

A copy of liburing 2.1 must be symlinked into vendor/ (a compile bug exists in newer versions, bundling may happen at a later date)

Requies a Linux kernel within the last two years, for io_uring features.

Building

Download and symlink or mv a copy of liburing 2.1 into vendor/liburing make

Sorry about the bare makefile; low priority :)

Start options

--conf [file.lua]
 - The test configuration to load/run.

--ip [127.0.0.1]
 - IP address to connect to

--port [11211]
 - port to connect to

## Configuration

See conf/example.lua for an introduction to the configuration language.

Please keep in mind: This is a benchmark tool, and as such we try to minimize
overhead. There is minimal argument checking, minimal error handling, etc. Try
to keep configuration files straightforward and simple.
