Overview

A small utility to benchmark different approaches for building concurrent applications.

Pre-requisites

1. cargo - https://www.rust-lang.org/tools/install
2. python3.6+ with matplotlib

Run batched/atomic/mutex increments benchmark

cargo bench

Command line options

``` A tool to model sync vs async processing for a network service

USAGE: concurrency-demo-benchmarks [OPTIONS] --name --rate --num_req --latency [SUBCOMMAND]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -l, --latency Comma separated latency values. E.g. 200,200,200,500 -N, --name Name of the test-case -n, --numreq Number of requests. E.g. 1000 -p, --pythonpath Optional path to python3, e.g. /usr/bin/python3 -r, --rate Request rate per second. E.g. 100 or 1000

SUBCOMMANDS: async Model a service with Async I/O help Prints this message or the help of the given subcommand(s) sync Model a service with Blocking I/O

Run sync demo

• 1000 rps
• 200ms latency (stable)

• 500 threads concurrency-demo-benchmarks -N sync_t500_200ms -r 100 -n 1000 -l 200 sync -t 500

• 1000 rps

• 600ms latency (stable)

• 500 threads concurrency-demo-benchmarks -N sync_t500_600ms -r 100 -n 1000 -l 600 sync -t 500

• 1000 rps

• 200ms latency but 30s for 10%
• 500 threads concurrency-demo-benchmarks -N sync_t500_30s -r 100 -n 1000 -l 200,200,200,200,200,200,200,200,200,30000 sync -t 500
