A minimal reproducing sample of some poor message receiving performance with tonic/tokio gRPC bidirectional streams.

Setup

• This has been tested on Ubuntu 20.04
• The multi-node run (./run.sh) requires Docker and Docker Compose:
• Install Docker:

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/do  cker-archive-keyring.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] ht  tps://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
sudo systemctl start docker # Docker will start automatically on future system boots

• Install Docker Compose v2:

sudo apt-get install docker-compose-plugin
docker compose version

• Set Docker to run without sudo:

sudo groupadd docker
sudo usermod -aG docker $USER
sudo reboot
docker run hello-world # This should work without sudo now

Run

• ./run.sh to build the binary and run the network of nodes. Define the number of nodes in the network in the .env file. By default this creates 75 nodes in a fully connected mesh network and attempts to create and share 225 signatures between every node. CPU usage is never high. Most messages are received imemdaitely and the remaining messages take about a minute.
