Investigate back-end performance of CNCF

[cjyabraham]

Sometimes when logged in to the site (and so not-cached) I experience some very slow load times.

Problem areas found:

1. people query takes 13s or more to execute at times
2. Many Custom Twitter Feed admin-ajax calls that ends up pulling an external resource such as this Kubecon sched, causing load times up to 23s

I can try and optimize 1.

For 2, likely we'd need to try a different plugin if it's a problem. It looks like it's asynchronous and independent of the page load process.

Deployed fix for 1. Will check on reports in a few days to see what else might bubble up.

1 is fixed and there are no other slow pages in the reports.
