So... why not use a different threshold?
I propose 80% for packages bigger than 200k, and 50% for smaller packages.
Yes, we could do that. The drawback is that it also takes a lot of time to reassemble the rpm from the deltarpm (the payload has to be compressed again, an operation that isn't cheap), so I used a fixed percentage.
I remember the discussion. But unless you have a download bandwidth greater than the recompression bandwidth, it should work out fine. And recompression bandwidth is quite big (MB/s). But, more importantly, bandwidth depends on the user, not the server. OBS should generate the deltas, and zypper should be told not to use them unless it's worth it (which is a simple function of known bandwidths). The server cannot make that decision. In my case, with a 1Mbps connection, recompression is quite a bit faster than download.
From the server's perspective, saving bandwidth should be top priority.
