We want to optimize for users seeing pages as fast as possible so we look at the three main components that contribute to the performance of a page load: network time, generation time, and render time.

FAST Facebook Results – new training course by Mari Smith NEW from Mari Smith: Facebook Ads Strategy Training + Facebook Live Video Success Secrets .

This was great progress, but in the meantime, Facebook had exploded in popularity all across the globe and we needed to start thinking about a worldwide audience.

Fast Facebook

We decided to measure TTI at the 75th percentile for all users as a better way to represent how fast the site felt. After looking at the data, we set an ambitious goal to cut this measurement in half by ; we had about six months to make Facebook twice as fast. Six Months and Counting On closer inspection, our measurements told us that pages were primarily slow because of network and render time. Our generation time definitely had and still has significant room to improve but it wouldn't provide the same bang for the buck.

So we devoted most of our engineering effort towards two goals: Before the development of this component library, each page would rely on a lot of custom HTML and CSS even though many pages shared similar features and functionality. These dramatic reductions mean we get our content to users faster and browsers can process it more quickly. Cutting back on JavaScript was another challenging problem.

Facebook feels like a dynamic and engaging site in large part due to the JavaScript functionality we've created, but as we added more and more features, we wrote more and more JavaScript which users have to download to use the site. Remember that downloading and executing JavaScript are two of the main issues we need to combat to improve network and render time.

To address this problem our engineers took a step back and looked at what we were using JavaScript to accomplish.

We noticed that a relatively small set of functionality could be used to build a large portion of our features yet we were implementing them in similar-but-different ways. This common functionality could be provided in a very small, efficient library that is also cacheable on the user's computer. Since Primer is downloaded quickly and then cached for use on future page views, it also means that features built exclusively on Primer are immediately usable when they appear on the screen; there's no need to wait for further JavaScript to download.

An example of such a feature is our feedback interface which allows users to comment on, like, and share content and appears all across Facebook. Another project I'd like to highlight requires a little more setup.

As described earlier, the traditional model for loading a web page involves a user sending a request to a server, the server generating a response which is sent back to the browser, and the browser converting the response in to something the user can see and interact with. If you think about this model there is a glaring problem.

Let's say it takes a few hundred milliseconds for the server to completely prepare and send a response back to the user. While the server is chugging through its work the browser is just sitting there uselessly, waiting for something to do and generally being lazy. What if we could pipeline this whole procedure?

Wouldn't it be great if the server could do a little bit of work, say in ten or fifty milliseconds, and then send a partial response back to the browser which can then start downloading JavaScript and CSS or even start displaying some content?

Once the server has done some more processing and has produced another bit of output it can send that back to the browser as well.

Then we just repeat the process until the server has nothing left to do. We've overlapped a significant portion of the generation time with the render time which will reduce the overall TTI experienced by the user. Over the last few months we've implemented exactly this ability for Facebook pages.

We call the whole system BigPipe and it allows us to break our web pages up in to logical blocks of content, called Pagelets, and pipeline the generation and render of these Pagelets.

Looking at the home page, for example, think of the newsfeed as one Pagelet, the Suggestions box another, and the advertisement yet another. BigPipe not only reduces the TTI of our pages but also makes them seem even faster to users since seeing partial content earlier feels faster than seeing complete content a little bit later.

I'm pleased to say that on December 22nd, as a result of these and other efforts, we declared victory on our goal to make the site twice as fast. We even had 9 whole days to spare!

One thing I have learned so far on my FB fast is that it is very liberating to not have to check FB every five minutes after I've posted something to see who liked it or commented.

On this fast, I also noticed when I'm out in public that a lot of people are tied to their mobile devices.

Countless times I have gone out to dinner with a friend only to notice people around us literally sitting in front of each other at the table and focused on their devices rather than engaging in conversation with the one sitting in front of them.

One of the reasons I got off of FB was so that I could unplug, re-set and begin dreaming about what God has for me in the upcoming season without any distractions. I wanted to go back to my mystic roots and become a minimalist once again in this season.

Opinions about Fast Facebook

Silence is one of my love languages and I love to sit at the lake for hours and just think. With FB in my life however, I was regularly distracted and torn between the beauty in front of me and the false sense of connection I felt by looking down at my phone. I wanted my thoughts to be pure, refined, and deeper than what FB required from me. I was also getting ready to dive into writing my next book and I wanted it to come from a deep well, not something fragmented, impulsive, shallow or flashy.

I was reflecting on what it must have been like for someone like Jane Austin to write a book. Long days with lots of silence, quiet space, and time to think deep thoughts. I felt that there might be a deep place in my heart I could explore more fully.

I knew that to get to the depths of that journey inward, I would need to be unhindered by any distractions. So now, into the second month of my FB fast, I am continuing to enjoy a simpler and more focused life. I'm journaling more, spending more time outside enjoying the summer with friends, climbing mountains and having deeper conversations without being distracted.

I'm reading more books, spending more time with family, and letting my heart feel at a deeper level. I'm deep cleaning and purging my house and my life it seems. I'm getting more focused on the Lord and praying more often.

I'm learning to grow in vulnerability, be uncomfortable and remain with the people in front of me rather than escape by looking down at my phone all of the time. I'm also praying about what my relationship with FB will be like in the future. If we ever do get back together, I want to set some good boundaries so that I can limit myself to the constant infiltration of words, videos, pictures of others' lives and begin to live my life more fully in the present.

I want my relationship with FB to be life-giving to myself and to all of my "friends. So if or when I do ever return to FB, I want there to be purpose in this relationship. I want to utilize FB so it becomes a blessing rather than let it control and take over my life. So that's my story in case some of you wondered where I disappeared to.

Hope you enjoyed the journey. Life is too short to waste it looking down all the time, unless of course, it's something special like this If you feel the need to cut back on your FB use, one way is to remove the FB app from your phone.

Another is to only check FB one day a week or whatever you feel works well with you.Click here to subscribe to our newsletter. December 14, - Facebook announces that a bug allowed third-party app developers to access photos people may not have shared publicly.

Rather than posting a picture for the masses, I had to redefine how and who I would want to share these experiences with. Since I'm usually all or nothing, I felt I needed to completely unplug to break this addiction. Since Primer is downloaded quickly and then cached for use on future page views, it also means that features built exclusively on Primer are immediately usable when they appear on the screen; there's no need to wait for further JavaScript to download.
