I just updated Komplete. It's been downloading all night, and is still not done.
Doing a back of the envelope calculation, I'm getting maybe 50 Mbit/s download. My connection is a usually reliable 1 Gbit fiber connection.
I'm on the West coast of the US — are the files all stored in a single server in Germany or something? It feels to me as if "downloading lots of large files" has been a solved problem for the last 15 years already…
