1 process on a 1X dyno, 2 processes on a 2X dyno, and 12 processes on a PX dyno. 1 process on a 1X dyno, 2 processes on a 2X dyno, and 12 processes on a PX dyno.
For example, when your app starts:
```
app[web.1]: Detected 1024 MB available memory, 512 MB limit per process (WEB_MEMORY)
app[web.1]: Recommending WEB_CONCURRENCY=2
app[web.1]:
app[web.1]: > example-concurrency@1.0.0 start /app
app[web.1]: > node server.js
app[web.1]: Listening on 51118
app[web.1]: Listening on 51118
```
Notice that on a 2X dyno, the
[example concurrency app](https://github.com/heroku-examples/node-concurrency)
listens on two processes concurrently.
