We have just finished creating a website for a client in MVC 4, the site has been deployed online too, but now the client complains about serious slow loading times. We cannot reproduce the problem by browsing the same site on our machines.
To start investigating the problem, we connected a new Relic to our server and are tracking the application, and this is what we see:

In WebTransaction, there is a massive response time of 57.900 ms, the problem is that we have no idea what exactly is happening in this web transaction and how to solve it.
Has anyone ever seen this? How can we solve this problem with huge load times?
Thanks,
asp.net-mvc-4 newrelic
