Red Hat Bugzilla – Bug 472140
yum selects slow mirrors
Last modified: 2014-01-21 18:06:47 EST
Description of problem:
I ve done many fresh fedora installations (9 or 10 preview) and performing updates as usual.
Downloading speed is very slow (around 30-50 kb per seconds)
So i manually edit repos and add (for example) a german server.
Now download speed is 10 times faster or more.
I have seen many complaints about updates download speed in local Greek forums.
This slowness give the false impression that yum or packagekit is extremely slow (endless downloading filelists or packages).
This problem maybe related with Greek servers that yum selects.
Any thoughts or solution about all these?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
You could try installing yum-fastestmirror, apart from that it's all data from MirrorManager.
shows me that there are two mirrors in Greece. When there are less than three mirrors in your country, MirrorManager adds mirrors from your same continent to the list, and then tries to send you to one of those mirrors with fast bandwidth (mirrors with gigabit speeds are chosen more often than mirrors with only 100Mbits).
What mirrors appear for you when you hit this page (you can do it from a web browser)? Alternately, what is your IP address?
I get those 2 when i hit your link:
i tried with firefox to download some packages directly from these sites.
1) was ok
2) is downloading about 20-30 kb/second
2) is a few kilometers near my home :)
MirrorManager propably selects this one (pressing ctrl-c during yum install shows its address). Is nearby but it is too slow.
So the situation here in Greece is:
Many users will have problems if MirrorManager selects ftp.cc.uoc.gr
Can you fix it to select the faster one. One user that installed yum-fastermirror told me that didnt solve this speed problem. Anyway this is an extra headache that will cause some (not needed) confusion to new greek users of fedora.
Dimitris, Nikos is reporting that your mirror is exceedingly slow. Care to investigate? MirrorManager lists you as capable of serving at 100Mbits/sec, but he is reporting 20-30Kb/sec.
new problems with this particular mirror
message: permission denied
http://ftp.cc.uoc.gr/pub/fedora/linux/releases/10/Live/i686/F10-i686-Live.iso when you hit download now button from http://fedoraproject.org/get-fedora
Can you either run another rsync or manually do the bitflip? releases/10 is still not readable from your mirror.
I've administratively lowered the bandwidth on this mirror to 1. Dmitris, please change it through the MM web interface to whatever value is correct once you've fixed it (i.e. done the bitflip)
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
A good idea in my opinion is to remove this server immediately (until problems are resolved).
Speed unfortunately is getting slower <20k and many users will auto redirected to this server.
I think also preupgrade is affected too.
The server (ftp.cc.uoc.gr) has 100Mbit upload to it's upstream provider.
which is full 24/365.(In reply to comment #4)

The server is capabe of serving at 100Mbps and actually it does
at 100Mbps 24/365.
sorry but we cannot serve each user at 100Mbps ...
btw the mirror is not dedicated to fedora.
Actually most requests are for other distributions.
if the server is slow for some users then
yum-fastestmirror should be able to redirect them to another
If yum-fastestmirror does not redirect them to another mirror
then it's a yum-fastestmirror's bug and NOT a server problem.

Giannis is right (Comment #10 From Kapetanakis Giannis).
Yes, on Nov 25th F10 was not available, but on Nov 26 it was. I actually
encouraged some friends around Europe to download from our
server -- since many of the fedora mirrors were outdated till then.
They didn't experience any problems/delays.
Enough said :)
plz Jon, change it back to 100 Mbps. The MM interface insists on keeping
1 Mbps (another bug?). I have already tried to change it 4 times(!)
Niko, check your provider's status. For domestic networks HOL reports
ok, Forthnet doesn't.
Take care ...
The server has been modified in order for Greece to have priority
in traffic, via GeoIP.
Things should be a little bit better now for local users.
Yes, MM has a "bug" in the caching of data entered via the web forms, whereby you can change a field, hit save, and then it doesn't appear as if the data was saved. I haven't figured out a way around TG's "all or nothing" caching model yet. I hear TG2 may be better at this.
Giannis: your server lists as 100 now.
As server has been adjusted, closing.
