I'm having troubles with downloading files from S3, If I download a file like 200MB, and then i download another files, the download speed it's just really slow like (40KB/s) as you can see in the follow pic:
And when the first download finish, the second continues with the 40KB/s...
Any ideas about that?
Amazon S3 has huge bandwidth.
If you are downloading from Amazon S3 to your own computer (outside of AWS), then the only limitations that would impact you are your own Internet bandwidth, and any speed limitations imposed within your own network.
I will presume that you are downloading an object from Amazon S3 to an Amazon EC2 instance in the same region as the S3 bucket.
In this scenario, the only bandwidth limitation is the Network Performance on the Amazon EC2 instance. Basically, the bigger the instance, the more bandwidth is available.
In the Launch screen, a t2.large is listed as Low to Moderate Network Performance. This is reasonably good, but not as good as larger instance types.
See:
It might also be a result of the software you are using to download the files and how it multi-tasks and shares network bandwidth between the downloads.
If you're connected to the Internet via WiFi router from your laptop, try to use cable connection instead.
