We're running a webzine on WordPress, our visitors are from all over the world.
We used Joomla before but switched to WordPress in august 2011.
We like WordPress above Jooma but since the switch our traffic has increased with 500% (about 1,5Gb per day at this moment) whereas the number of visitors per day have increased with only 10%.
We've done everything to keep the traffic usage on our webzine as low as possible like using links to pictures on picasa/flickr instead of hosting the images ourselves (except for small previews).
My question is: How do I figure out what part of the website or which plugin is causing this huge datatraffic?
Our webhost is offering webalizer stats and in there I can see most hits are generated by 18.104.22.168 which is an IP address from Google I found out. I guess that should be all right then…. right?
Then there is another strange host address that is generating the most traffic and has a really strange host address: 2a01:7c8:eb:0:95:170:70:251
I did an whois on that address and it turns out to be our own webhost, why is it generating so much traffic???
Can anyone give me advice how to investigate this matter? What is the best approach?
We are gong to tripple our traffic limit per month which will bring a lot of costs to us.
Thanks in advance
