Here's the initial issue statement, received via email:
Lena asked me to provide you additional information regarding the download issue.
We provide our data on two ways (https://www.synapse.org/#!Synapse:syn18779624/files/):
As single files that can be downloaded via a script
As zip file
In both cases we receive emails from user that they can't download our data or that the download is really really slow. Overall, the size of our dataset is >400GB
What can we do to enable our participants a faster download?
Here are responses to my clarifying questions:
When you say "from user" do you mean one user mentioned the issue or more than one? If more, how many? How many total users are downloading the data? Do you yourself find that the data download is slow?
Currently we are having 30 registered participants of our challenge and all of them need our data.
I got 8 messages that they have problems to download the data. All of them are talking about a slow download rate. They also mention that the download stops very often.
Yes, I also find the download with <10Mbps slow.
When you say "really really slow", can you quantify that? How fast do you expect the download to be? When you say "can't download our data" can you explain what the symptom is, for example is there an error that is seen? Can you see the error (and, perhaps, send us a screen shot)?
At my institute we are having a download speed capacity of ~740.39Mbps but downloading your data just goes with a speed of 10 Mbps. So currently it would take me ~4 days to download the data.
For me I would be happy with a download time of 8h (~100Mbps) for this data size.
I didn't got a network out of time error so far or a cancellation of my connection, but I can ask the users for screenshots.
