Getting rpc-perf

rpc-perf is built through the cargo command which ships with rust. If you don't have Rust installed, you can use rustup to manage your Rust installation. Otherwise, follow the instructions on rust-lang.org to get Rust and Cargo installed. rpc-perf is developed and tested against the stable Rust toolchain.

Build from source

With Rust installed, clone this repo, and cd into this folder:

git clone https://github.com/twitter/rpc-perf.git
cd rpc-perf
cargo build --release

This will produce a binary at target/release/rpc-perf which can be run in-place or copied to a more convenient location on your system.

Configuration

rpc-perf takes a configuration file to define the test parameters and runtime options.

Sample Usage

BEWARE rpc-perf can write to its target and can generate many requests

run only if data in the server can be lost/destroyed/corrupted/etc
run only if you understand the impact of sending high-levels of traffic across your network

# run rpc-perf using the specified configuration file
rpc-perf configs/memcache.toml

Practices

Start with a short test before moving on to tests spanning larger periods of time
If comparing latency between two setups, be sure to set a ratelimit that's achievable on both
Keep --clients below the number of cores on the machine generating workload
Increase --poolsize as necessary to simulate production-like connection numbers
You may need to use multiple machines to generate enough workload and/or connections to the target
Log your configuration and results to make repeating and sharing experiments easy
Use waterfalls to help visualize latency distribution over time and see anomalies

Features

high-resolution latency metrics
supports memcache and redis protocols
mio for async networking
optional waterfall visualization of latencies
powerful workload configuration
