The document discusses website performance and optimization. It notes that nearly half of users expect a site to load within 2 seconds and will abandon a site taking longer than 3 seconds. Common issues causing poor performance are bloated templates, unnecessary code, and too many HTTP requests. Suggested optimizations include minimizing assets, prioritizing visible content, image optimization, caching, compression, and lazy loading. Case studies show significant speed improvements after implementing optimizations. Metrics like Speed Index measure how quickly visible content displays to influence perceived performance.

Make Drupal Run Fast - increase page load speedAndy Kucharski
What does it mean when someone says “My Site is slow now”? What is page speed? How do you measure it? How can you make it faster? We’ll try to answer these questions, provide you with a set of tools to use and explain how this relates to your server load.
We will cover:
- What is page load speed? – Tools used to measure performance of your pages and site – Six Key Improvements to make Drupal “run fast”
++ Performance Module settings and how they work
++ Caching – biggest gainer and how to implement Boost
++ Other quick hits: off loading search, tweaking settings & why running crons is important
++ Ask your host about APC and how to make sure its set up correctly
++ Dare we look at the database? Easy changes that will help a lot!
- Monitoring Best practices – what to set up to make sure you know what is going on with your server – What if you get slashdoted? Recommendation on how to quickly take cover from a rhino.
This document discusses ways to improve the speed of a website. It identifies several methods: checking loading times; selecting an appropriate hosting provider; optimizing content like images; removing unnecessary plugins; employing caching; using a content delivery network; and optimizing the database. Faster sites boost rankings, conversions and traffic. Regular maintenance is needed to ensure optimal performance over time.
Today, a web page can be delivered to desktop computers, televisions, or handheld devices like tablets or phones. While a technique like responsive design helps ensure that our web sites look good across that spectrum of devices we may forget that we need to make sure that our web sites also perform well across that same spectrum. More and more of our users are shifting their Internet usage to these more varied platforms and connection speeds with some moving entirely to mobile Internet.
In this session we’ll look at the tools that can help you understand, measure and improve the web performance of your web sites and applications. The talk will also discuss how new server-side techniques might help us optimize our front-end performance. Finally, since the best way to test is to have devices in your hand, we’ll discuss some tips for getting your hands on them cheaply.
This presentation builds upon Dave’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.”
This talk was given at the Responsive Web Design Summit hosted by Environments for Humans.

The document discusses strategies for optimizing WordPress performance and scalability as website traffic grows. It recommends optimizing the WordPress configuration, disabling heavy or unnecessary plugins, enabling caching plugins like WP Super Cache, and using a content delivery network to offload assets. As traffic increases, the document suggests moving from shared hosting to virtual private servers or dedicated servers to allow configuration changes. It advises a scale-out approach adding more web servers behind a load balancer and scaling databases for redundancy as needed. The key is optimizing WordPress for performance early and scaling infrastructure ahead of traffic growth.
Web performance optimization techniques include:
- Choosing an optimal hosting provider
- Combining and minifying files to reduce size
- Implementing caching at multiple levels (e.g. frameworks, databases)
- Using content delivery networks
- Optimizing database and SQL queries
The document provides best practices and examples for optimizing websites using techniques like caching plugins, query optimization, indexing databases, and monitoring tools.

Faced with the impossibility of Dilma Rousseff and Michel Temer build social peace in Brazil would need to be the resignation of both, respectively the Presidency and Vice-Presidency of the Republic to make way for the establishment of an interim government of national unity composed of respectable public figures accepted by all political forces in confrontation that would have the mandate to convene a new constituent assembly to reorganize the national life, seek the country's consensus in resolving the economic and social crisis, prevent the escalation of violence in Brazil and hold new general elections in the country . This would therefore be the way to avoid a fratricidal struggle or a civil war in Brazil when the dissension would remove the construction of a new social pact. If this policy solution is not adopted there will only be one outcome to the institutional impasse in which he lives the Brazilian nation that is the intervention of the armed forces for the maintenance of constitutional order to prevent the emergence of a civil war in Brazil.

Boston Web Performance Meetup: The Render Chain and Youmattringel
Joseph Morrissey and Matt Ringel from Akamai Technologies go a level deeper into web browser internals to show how a browser turns HTML into pixels, and what you can do with your web pages to make them easier to digest by the browser.
We include the top 5 things we've found that make web site rendering slower, and what you can do to fix them.
2. Why Should We Care about Website
Performance ?
“ Nearly half of the web users expect a site to load in 2
seconds or less, and they tend to abandon a site that isn’t
loaded within 3 seconds, according to Akamai and
Gomez.com”
3. WEBSITE PERFORMANCE – FACTS AND STATS
• 47% of consumers expect a web page to load in 2 seconds or
less
• 40% of people abandon a website that takes more than 3
seconds to load
• 75% of the 1,058 people asked would not return to websites that
took longer than four seconds to load
• A 1 second delay in page response can result in a 7% reduction
in conversions
• If an e-commerce site is making £100,000 per day, a 1 second
page delay could potentially cost you £2.5 million in lost sales
4. WEBSITE PERFORMANCE – FACTS AND STATS
Average web page size, with an average of 95 HTTP pull requests
per page
6. MOST COMMON REASONS FOR A POOR PERFORMANCE
• Bloated CMS Templates
Typical WordPress themes are crammed full of features. Many will be third-party
styles and widgets the author has added to make the theme more useful or
attractive to buyers. Many features will not be used but the files are still present
• HTML5/CSS3 Boilerplates
A boilerplate may save time but it’s important to understand they are generic
templates. The styles and scripts contain features you’ll never use and the
HTML can be verbose with deeply-nested elements and long-winded,
descriptive class names. Few developers bother to remove redundant code
• Carelessness
Developers are inherently lazy; we write software to make tasks easier.
However, if you’re not concerned about the consequences of page weight, you
should have your web license revoked
• Too many requests
Each request takes time to process, as it includes time for DNS Lookup, SSL
8. PERFORMANCE OPTIMISATIONS
• Cleanup Code
Remove comments, remove unnecessary HTML, JS and CSS
• Combine and Minify Assets (JS and CSS)
Combine the JS files and libraries into one JS file and minify. The same for CSS
to reduce number of requests
• Load CSS on the <head> and JS just before </body>
Loading CSS first, prevents additional repaints and reflows, and will make the
page look much better from the beginning and JS in the end to allow for the
page to be rendered without being blocked while loading the scripts
• Try to load scripts as asynchronous
This way, the page rendering won’t be blocked and triggers the
$(document).ready() ,much sooner. All social media plugins and analytics
should be loaded asynchronously
• Make use of sprites whenever possible
9. PERFORMANCE OPTIMISATIONS
• Cache
Make an effective use of cache. Cache assets, cache DB queries, cache
templates / pre-render templates. Also implement Cache Busters. The preferred
URL fingerprint is /assets/9833e4/css/style.css, as other solutions might have
problems with proxies and CDNs
• Download assets from cookieless domains
It saves a lot of time, when requesting the assets
• Download assets from multiple subdomains / CDNs
static.domain.com, static1.domain.com, etc, as browsers usually have a limit on
how many concurrent connections they establish with each domain, which
means, the first set of assets, needs to be downloaded before starting new
connections
• Consider using Google CDN
Google CDN is usually very fast, and physically close to the client. And the client
might already have the asset cached
10. PERFORMANCE OPTIMISATIONS
• Enable Compression
Enabling compression (e.g. GZIP) to make the file size much smaller to
download. With jQuery ou can get a gain of 88% when compared to the original
size – jQuery (273K), Minified (90k), Compressed (32K)
• Remove inline scripts and styles
Move them into files to make them cacheable
• Serve adequately sized images
If we only need a 50x50px image, just serve that image. Don’t rely on the
browser to resize, as it will still download the full size image
• Optimize images
Remove unnecessary data from images (strip irrelevant information), compress,
and if it is a JPEG, make use of the progressive version, as this will make the
image start appearing sooner
11. PERFORMANCE OPTIMISATIONS
• Prevent excessive redirects
Each redirect costs time, so avoid unnecessary redirections
• Consider using Nginx for serving static content
Nginx is very fast and optimised to serve static content
• Consider using techniques like lazy loading
If the content is not important for SEO or another reason, consider triggering the
load, only after the page is served
• Consider hosting images, web server and database server in a
different machines
This reduces the load on each server, which translates in faster response times
12. Real Speed vs Apparent Speed
“Even if we optimise all the aspects, we might still have a
website that’ll take longer than we wished for. We can make
use of several techniques to make the site apparently faster.”
13. INTRODUCING WEBPAGETEST.ORG SPEED INDEX
The Speed Index is the average time at which visible parts of the
page are displayed. It takes the visual progress of the visible page
loading and computes an overall score for how quickly the content
painted. The lower the number the better.

Just to mention that this is on a project by project basis. Some improvements might not be worth considering, depending on bugdet, project duration, time schedules
This is “extreme” optimisation
Images are the greatest chunk
Simultaneous connections (6) which means resources will have to finish download before starting a new connection.
Alternative would be using parallel connections from different domains
Since crawlers/spiders are robots, we need to help them to understand the content, by using the correct meta tags, semantic tags, alt attributes
You can clearly see when they were implemented by looking at the graph
See links and show the video feature, the dom load event vs page load, and even events loaded after the page load
Talk about the number of requests, use sprites
See webfont example
