attention brno folks: testing wanted

[Kevin Fenzi]

Hey everyone.

A while back we had reports from folks particularly in Brno that
operations to pagure.io were very slow. We put in place a workaround
while we worked on the issue with network providers and tried various
things. I'd like to know if any of those things have fixed (or at least
made better) the issue.

So, if you had slow pagure connections in the past, can you:

* do some initial tests:

time git clone https://pagure.io/pagure.git

time curl https://pagure.io/pagure/issue/3714

time curl https://releases.pagure.org/virt-viewer/virt-viewer-x86-7.0.msi

* then add:
140.211.169.204 pagure.io
or
(if you use ipv6):
2605:bc80:3010:600:dead:beef:cafe:fed8 pagure.io

to your /etc/hosts file

* Then run the tests again:

time git clone https://pagure.io/pagure.git

time curl https://pagure.io/pagure/issue/3714

time curl https://releases.pagure.org/virt-viewer/virt-viewer-x86-7.0.msi

* Then remember to REMOVE the hosts entry so it's not there later
causing you confusion.

Thanks in advance for any testing.

Hey,

I'm from Poland, which is close enough to Brno and far away from Pagure.
Tests times are similar:

real 0m12.774s
user 0m3.900s
sys 0m0.881s

real 0m1.417s
user 0m0.017s
sys 0m0.012s

real 0m0.977s
user 0m0.017s
sys 0m0.007s


With forced DNS entries:

real 0m14.382s
user 0m4.004s
sys 0m0.856s

real 0m1.244s
user 0m0.016s
sys 0m0.008s

real 0m0.854s
user 0m0.016s
sys 0m0.007s


My network connection is residential, symmetrical 100MBps. As Fedora
developer I've pagure.io cached in resolver probably, so the tests
may not be relevant.

Honestly, I'm not sure what to conclude from this.
