Uploading IUKs to rsync.lizard is slow
When there are reproducibility issues with IUKs, the RM needs to upload their IUK to rsync.lizard. This is very slow. I was around 100kB/s, while my network connection easily allows 10MB/s. In retrospect, I could have done this very differently, which would have made my life easier.
I think we should:
- check if there are ways for us to get much faster SSH connections
- if there aren't, document some trick. For example, we could upload to some filelocker and then redownload and verify hashes again
