Description Jargon Scott 2015-06-11 18:54:15 EDT
Description of problem:

Yum supports a "max_connections" parameter, which allows the user to tune the maximum number of simultaneous downloads.

Although DNF supports parallel downloads, I see no means by which the user may *change* the maximum number of concurrent downloads.

Such a feature is desirable, for example, on flaky or unreliable network links.  In these cases, it's useful to set yum's max_connections=1 to maximize the number of packages that have been downloaded completely and cached before the link goes down.

Version-Release number of selected component (if applicable):


How reproducible: Always (this is a feature request).

Steps to Reproduce:
1. dnf install foo

Actual results:

Progress meter indicates that two packages are being downloaded simultaneously.

Expected results:

Upon setting a dnf configuration parameter, the progress meter should confirm that 1 (or 3 or ... ) packages are being downloaded at a time.

Comment 3 Jargon Scott 2015-07-24 21:10:05 EDT
Thank you very much!

I can confirm that this works for me when setting max_parallel_downloads=1 in /etc/dnf/dnf.conf .
