Issue #7212
Updated by bmbouter over 3 years ago
There are reports that the download concurrency is too high, like this one: https://pulp.plan.io/issues/7186#note-4 So we should lower the concurrency limit. We need to balance the stability gained from a lower concurrency against the lost speeds from parallel fetching. Can someone measure the runtime of a `policy=immediate` sync with the following download_concurrency values: 20, 15, 10, 7, 5, 20 15 10 7 5 3 Pulp2 had a value of 5. Other download softwares like bandersnatch have a value of 3, so one of those is the most likely choice. We should understand how the performance degrades though so running this test would be nice.
