Thanks,

6. How do I change the mirror?
- I've tried but doesn't works, and I understand the branching and used it correctly. (/etc/yum.repos.d/fedora.repo and /etc/yum.repos.d/fedora-updates.repo)
- The error I get is `Cannot download repodata/repomd.xml:`

P.S. I see there is little information about this, can I use this data to share it on askfedora?

Hi!

I'm from Romania, the speed from Fedora repo mirror is very low (from
50kb/s to 1 mb/s when it's good, usually the download speed stays
between 50 and 150 kb/s with the official repos and over 1 mb/s with
other repos ) when doing updates and when I install packages with
dnf. I tried using fastmirror module but I see there is no change and
I lose even more time because of the search for the best mirror.

Does it always send you to the same mirror? 
Using 'dnf -v' should tell you.

1. What can I do to resolve this issue?

Well, if you can find a better mirror you could hard code it. 
Or if you can find out which one is slow, mirrormanager admins could
remove or adjust it.

2. Is there a way to manually test mirrors and chose the best one for
me?

You can get the full list from: 
https://admin.fedoraproject.org/mirrormanager/

3. How do I know witch mirror can I trust?

Any of them. If you are using the default metalink it has checksums of
all the files. If you are not, all rpms are signed, so if they were
tampered with they would be rejected.

4. Where can I find a mirror list?

https://admin.fedoraproject.org/mirrormanager/

5. How can I create a local mirror?

Hope that helps.
