IMHO, the issue is too much data and too little bandwidth. So I suggest we first look at:
a) why is there too much data? b) why is there too little bandwidth?
Indeed. a) AIUI because we transfer the same big data to 60+ mirrors at the same time from this one central location. A problem that bittorrent solved by transferring between peers P2P. b) there is only a 4GBit/s link atm. Mikelis proposed to setup another dedicated 4GBit/s link just for openSUSE, but since we were already using >2.5GBit, that can only improve the situation a little. There will be a move to the Prague DC next year, that could give us up to 10GBit/s, but even with that, we should still think about improving the organization of the transfers.
Again, we should identify the issue first of all. As we know, it is insufficient bandwidth. If we cannot get more bandwidth, we have to prioritise what we send where and when.
I say skip the repositories push - it is persistently way behind, and despite my recent efforts to optimise it, it's not getting any better.
IMHO, repopush also suffers from the other 60 mirrors using up the shared bandwidth. repopush is not the problem. I think, it can even be part of the solution, because with it, we have better control over what gets pushed when. Ciao Bernhard M.
