Zenodo data upload speed

“Free” “unlimited” data storage, even for scientists doing multi-generational data archiving, has its bounds, else tragedy of the commons would result. For Zenodo as of this writing, with my end having a very high quality full-gigabit Internet connection, I get Zenodo upload speeds in the 5-20 Mbyte/second range, averaging about 12 Mbyte/second.

That means for the current 50 Gbyte per dataset limit, a 50 Gbyte upload will take me about 1 to 3 hours. Thus it’s useful to use good archival file compression before uploading to Zenodo or elsewhere.
