boost-redis-benchmark

A multi-write benchmark for Boost redis client

This benchmarks makes a relatively large number of HSET requests to the Redis server using Boost.Redis client.

Requirements

• C++20 compiler (tested on gcc 12)
• boost (tested v1.83.0, 1.84.0 develop, built with SSL support)
• boost::redis installed to the same directory as boost.

Install development version.

git clone --recurse-submodules -b develop https://github.com/boostorg/boost.git
cd boost
./bootstrap.sh
./b2 --layout=system \
    --with-system \
    --with-thread \
    cxxflags="-std=c++20 -fPIC" \
    cflags="-fPIC" \
    variant=release \
    link=static \
    -d0 \
    -j 8 \
    install

Build

Plain gcc command

g++ -std=c++20 batch_send_benchmark.cpp -o batch_send_benchmark -lboost_system -lssl -lcrypto

Make sure Boost and SSL can be found by GCC.

CMake build

mkdir build
cd build
cmake ..
cmake --build .

Run

./batch_send_benchmark [n_req [payload_size]]

where

• n_req is a number of HSET requests sent.
• payload_size is a number of characters in a payload string.

Details

All the boilerplate aside, this benchmark sends the requests to Redis in two ways. In the separate part, in function runSeparateRequestsOnce(), all the requests are sent for execution independently. In the combined part, in function runCombinedRequestsOnce(), all the HSET commands are put into the same request, which is then sent for execution.

The benchmark does three runs in a row: the first one contains only separate part, the second one contains only conbimed part, and the last one contains both parts.
