Description Ding-Yi Chen 2015-01-27 01:41:19 UTC

Description of problem:
For users that cannot connect to Google, Zanata is very slow.
It took about 1 min for each navigation.

For example, it took 1 min and 8 second from IBus-Chewing project page 
to master branch in https://fedora.zanata.org

Version-Release number of selected component (if applicable):
Zanata 3.5.1 (git-server-3.5.1)

How reproducible:
Always.

Steps to Reproduce:
1. Run following command to block Google services (iptables)
   iptables -I INPUT -s 64.233.160.0/16 -j DROP
   iptables -I INPUT -s 66.249.64.0/16 -j DROP
   iptables -I INPUT -s 72.14.192.0/16 -j DROP
   iptables -I INPUT -s 74.125.0.0/16 -j DROP
   iptables -I INPUT -s 209.85.128.0/16 -j DROP
   iptables -I INPUT -s 216.58.0.0/16 -j DROP
   iptables -I INPUT -s 216.239.32.0/16 -j DROP

2. Ensure you get no connection with Google by 
   ping -c 5 fonts.googleapis.com
   ping -c 5 google.com 

3. Log In to https://fedora.zanata.org or any other server
4. Search ibus-chewing
5. Go to ibus-chewing project page
6. Go to master branch

Actual results:
From 3. Each operation was extreme slow, took about 1 minute to complete each step.

Expected results:
Speed difference should not be significant.
