This year marks the first year that we are doing full scale rendering of our SPA application on our mobile.walmart.com Node.js tier, which has provided a number of challenges that are very different from the mostly IO-bound load of our prior #nodebf.
The infrastructure outlined for last year is the same but our Home, Item and a few other pages are prerendered on the server using fruit-loops and hula-hoop to execute an optimized version of our client-side JavaScript and provide a SEO and first-load friendly version of the site.
To support the additional CPU load concerns as peak, which we hope will be unfounded or mitigated by our work, we have also taken a variety of steps to increase cache lifetimes of the pages that are being served in this manner. In order of their impact:

Recently had a code review where the distinction between setInterval and setTimeout under Node came up. Wanting to answer this question I put together some simple tests. The behavior of the two implementations, as of Node 0.10.30, was surprisingly reverse of my expecations, but there is a lot of nuance to how the event loop works in this case.
setInterval's behavior is similar to what one would expect from a exec+setTimeout loop. It's period is going to be it's exec time plus the interval value.
setInterval Delay: 50 Interval: 100 Wait mode: none
