Overview

This repo contains both server and client used in oatpp-websocket-benchmarks. Both server and client are implemented based on oatpp Async API and oatpp-coroutines

Repo structure

|- client/
|    |- src/                    // client source code
|    |- CMakeLists.txt          // client CMakeLists.txt

|- prepare.sh                   // prepare script - will clone oatpp and oatpp-websocket. build and install.
|- sock-config.sh               // configure required sysctl(s)

Reproduce latest benchmark

Create two n1-highmem-16 (16 vCPUs, 104 GB memory) - Debian GNU/Linux 9 instances in same VPC on Google Cloud.

Execute the following commands for both instances (SSH).

  • Install git
$ sudo su
$ apt-get update
...
$ apt-get install -y git
...
$ git clone https://github.com/oatpp/benchmark-websocket
...
$ cd benchmark-websocket
  • Install oatpp and oatpp-websocket modules (run ./prepare.sh script).
$ ./prepare.sh
  • Configure environment (run ./sock-config-5m.sh script)
$ ./sock-config-5m.sh
$ ulimit -n 6000000

Build and Run Server

Commands for server instance only:

  • Build server
$ cd server/build/
$ cmake ..
$ make
  • Run server
$ ./wsb-server-exe --tp 16 --tio 8 --pc 500

where:
--tp - number of data-processing threads.
--tio - number of I/O workers.
--pc - number of ports to listen to.

Build and Run Client

Commands for client instance only:

  • Build client
$ cd client/build/
$ cmake ..
$ make
  • Run client
$ ./wsb-client-exe --tp 16 --tio 8 -h <server-private-ip> --socks-max 5000000 --socks-port 10000 --si 1000 --sf 30 --pc 500

where:
--tp - number of data-processing threads.
--tio - number of I/O workers.
-h <server-private-ip> - substitute private-ip of server instance here.
--socks-max - how many client connections to establish.
--socks-port - how many client connections per port.
--si 1000 --sf 30 - control how fast clients will connect to server. Here - each 1000 iterations sleep for 30 milliseconds.
--pc - number of available server ports to connect to.

Note - clients will not start load until all clients are connected.
Note - client app will fail with assertion if any of clients has failed.
