SBK

Storage Benchmark Kit

Memcached performance benchmarking with SBK

The Memcached driver for SBK supports single/multiple Writer , single/multiple reader performance benchmarking.

Setting up Memcached local Docker server

To make simple demo/test, you can run the local memcached server docker image as follows:

docker run --name memcached-server -p 11211:11211 memcached

make sure you have redirected the port 11211 from docker to local system

Now, you can run the Memcached benchmarking as follows.

sanjaynv@DESKTOP-VMPKLNN MINGW64  - SBK Driver/SBK (master)
$ ./build/install/sbk/bin/sbk.bat -class memcached -writers 1 -size 100 -seconds 60 -url localhost -port 11211
