wring out every ounce of performance

The machine, of course, is not complete without a third party, the (human) operator, and it is within this triad that the text takes place.

It’s known that Angular becomes slower with around 2,000 bindings due to the process behind dirty-checking. The less we can add to this limit the better, as bindings can add up without us really noticing it!

Here are a few handy tips on measuring your project’s performance profile:

If your timeline graph is dominated with the color green after recording

there does not seem to be a general rule for how many workers to spawn. Some developers claim that 8 is a good number, but use an online calculator and suit yourself

The $digest loop keeps iterating until the model stabilizes

The value function should return the value which is being watched. AngularJS can then check the value returned against the value the watch function returned the last time

Both accessibility and performance are invisible aspects of an experience and should be considered even if they aren’t explicit goals of the project.

So instead we introduced the loading spinner on each widget. Nothing is actually any faster, but the whole experience feels more responsive

Simply reducing some CSS transition times from 500ms to 250ms, and cutting others out entirely, made the whole dashboard feel snappier and more responsive.

This means content is served from the nearest possible geographic location to the user, cutting down request latency from as high as 2500ms (in places such as Singapore) to tens of milliseconds

We eventually came up with a compromise solution based on Addy Osmani’s basket.js, using a combination of server-side script concatenation and localStorage for caching. In a nutshell, the page includes a lightweight loader script, which figures out which JS and CSS it has already cached and which needs to be fetched. The loader then requests all the resources it needs from the server in one request, and saves all the resources into localStorage under individual keys. This gives us a great compromise between cutting down the number of HTTP requests while still being able to maintain cacheability, and not re-downloading code unnecessarily when it hasn’t changed. Addtionally, after running a few benchmarks, we found that localStorage is (sometimes) actually faster than the native HTTP cache, especially on mobile browsers.

Is Your Performance Review System Outdated

High performing teams have well-defined goals, systems of accountability, clear roles and responsibilities, and open communication.

Instead of cheerleading, people in my profession should think of themselves as businesspeople. What’s good for the company? How do we communicate that to employees? How can we help every worker understand what we mean by high performance?

I replied, “Why bother? We know how this will play out. You’ll write up objectives and deliverables for her to achieve, which she can’t, because she lacks the skills. Every Wednesday you’ll take time away from your real work to discuss (and document) her shortcomings. You won’t sleep on Tuesday nights, because you’ll know it will be an awful meeting, and the same will be true for her. After a few weeks there will be tears. This will go on for three months. The entire team will know. And at the end you’ll fire her. None of this will make any sense to her, because for five years she’s been consistently rewarded for being great at her job—a job that basically doesn’t exist anymore. Tell me again how Netflix benefits?

HR people can’t believe that a company the size of Netflix doesn’t hold annual reviews. “Are you making this up just to upset us?” they ask. I’m not. If you talk simply and honestly about performance on a regular basis, you can get good results—probably better ones than a company that grades everyone on a five-point scale.

Traditional corporate performance reviews are driven largely by fear of litigation. The theory is that if you want to get rid of someone, you need a paper trail documenting a history of poor achievement. At many companies, low performers are placed on “Performance Improvement Plans.” I detest PIPs. I think they’re fundamentally dishonest: They never accomplish what their name implies.
