What do you guys think could happen if the post max size and max upload limit were set to 1GB in my php.ini?

Are there any precautions I need to have in mind?

I am using the basic plan with 3GB main memory.

You'll probably need to increase your max execution time as well to account for longer upload times with larger files. You may want to use something that will break uploads up in chunks instead though, like Plupload.

You definitely will need to increase the timeout (unless all your clients have super fast connections -- and even that may not help).
