How large is Crossbar.io?ΒΆ

Short answer

  • 258 kB as a download
  • 81 MB as a virtualenv
  • 187 MB as a binary package
  • 398 MB as a Docker container

Long answer

Crossbar.io itself is a download of less than 1 MB. However, Crossbar.io depends on a lot of other libraries and packages. It reuses proven solutions wherever possible. For this reason, when actually installing Crossbar.io, the footprint will be significantly larger than the download size of Crossbar.io suggests.

Here is what you get installing Crossbar.io into a fresh Python 3 virtualenv:

oberstet@thinkpad-t430s:~$ ./python351/bin/virtualenv ~/python351_3
Using base prefix '/home/oberstet/python351'
New python executable in /home/oberstet/python351_3/bin/python3.5
Also creating executable in /home/oberstet/python351_3/bin/python

You are using pip version 8.0.2, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
(python351_3) oberstet@thinkpad-t430s:~$ du -hs ~/python351_3/
81M /home/oberstet/python351_3/
(python351_3) oberstet@thinkpad-t430s:~$

That is **81 MB** installed size, compared to **254kB** download size for Crossbar.io alone.

Now, the virtualenv doesn't include the whole Python itself. Here is the Python underlying the above virtualenv:

oberstet@thinkpad-t430s:~$ du -hs python351 178M python351

Now, when you install Crossbar.io from our binary packages (recommended), you get:


```console
oberstet@thinkpad-t430s:~$ sudo apt-get install crossbar

oberstet@thinkpad-t430s:~$ du -hs /opt/crossbar/
187M    /opt/crossbar/
oberstet@thinkpad-t430s:~$

That's slightly larger, which is expected, since the binary package is fully self-contained, and it also runs PyPy (which is itself slightly larger than CPython). But 187 MB.

However, again, this doesn't contain the OS, only everything Python and above. So, here is what you get using OS containers, with the Crossbar.io for Docker image:

oberstet@thinkpad-t430s:~$ sudo docker images

So Crossbar.io is 398 MB when Dockerized.
