Node is an awesome platform to very easily write very well performing servers.

- Tracking Code and Click Response Delays - Ravelrumba ravelrumba.com
Aside from choosing not to install tracking solutions that come with such a performance penalty (which is not always an option), your best option is to replace the default 500ms timeout in these scripts with something less obtrusive. 100ms is considered the threshold for what we perceive as instantaneous response.
Good stats. "If you’re using jQuery on a public-facing site, use the Google CDN to host it." But don't use latest version in production.

- High Performance Web Sites :: WebPagetest.org and Page Speed stevesouders.com
One area where WPO needs more standardization is performance analysis. There are numerous performance analysis tools available, including Page Speed, YSlow, AOL Pagetest, MSFast, VRTA, and neXpert. There’s some commonality across these tools, but the differences are what’s noticeable. To get a thorough performance scrubbing, web developers have no choice but to run multiple tools and sift through the different results trying to find the most important recommendations. It would be better for developers to have a more standard way of analyzing performance across environments. The Page Speed SDK provides a path to achieve this.

I created a CSS test page, which started out as a crude way to figure out if there was a noticeable performance difference between SASS’s @extend and OOCSS’s method of CSS.
- High Performance Web Sites :: Diffable: only download the deltas stevesouders.com
Diffable uses differential compression to reduce the size of JavaScript downloads. It makes a lot of sense. Suppose your web site has a large external script. When a new release comes out, it’s often the case that a bulk of that large script is unchanged. And yet, users have to download the entire new script even if the old script is still cached.

django-devserver provides a simple drop-in runserver replacement. It allows you to run a command, python manage.py rundevserver, and to get some additional information. As of writing, that additional information includes real-time SQL logging (aka mass query spam in your terminal), and a summary of cache calls.
Not entirely buying all the arguments in this one but raises some very worthwhile points.
