Description of problem: dnf-makecache.timer make my network bandwidth higher than my prediction Version-Release number of selected component (if applicable): dnf-4.2.15 libdnf-0.37.2 How reproducible: Steps to Reproduce: 1.Deploy 4000 virtual machines at the same time 2.They trigger dnf-makecache.timer at the same time 3. Actual results: Expected results: Don't want to take up too much network bandwidth Additional info:
We will use the same timer randomization as is used with the dnf-automatic timers. Is that ok with you zhangrui?
I think it is OK
Hi lhrazky Sorry for disturbing you Can you reproduce the problem I asked? Do we really need this automatic service,because it does pose a risk to my system? thanks
Hi zhangrui, I didn't get to look into it yet, but I believe I don't need to reproduce, there is no randomization to the timer so we know the problem can occur. Are you saying you would prefer to not have the makecache timer at all? Is it possible for you to disable it before deploying the VMs?
