Size of Symfony2 project too big when using Composer

Question

First I downloaded Symfony2 framework (Standard Edition) from the official website and after installing it, the whole Symfony project had ~16MB in total.
After that, I wanted to start another Symfony2 project using Composer and create-project command. After installing, that application had ~130MB!
There is huge size difference between those two projects.
I suppose I downloaded some additional bundles when I used Composer, but the difference in size of more than 100MB seems to much.
I checked both projects and they have the same directory structure (i.e. I didn't find some additional directory in the bigger project).
So, why is there such a big difference and what I did wrong to have such a huge project when I used Composer.

Answer 1

It might be that you have git clones of the projects, in which case the size will be much bigger indeed. Try to remove the vendor dir and then run composer install --prefer-dist to make sure you only get the package files and no git information. If it makes no difference though, I guess that's just the file size it is.

Another discrepancy might be due to the fact the zips on symfony.com have a lot of stuff removed from the vendor directory. Tests and documentation of vendors are stripped, while composer will not do that.

In any case though, it's just files. Disks are pretty cheap. I would not worry about it too much.
