INTRODUCTION
 When you implement the Optimizely snippet according to our best practices, you 
may wonder how Optimizely will affect your site's load speed.
 Traditional web development best practices dictate that any third-party JavaScript 
file, like Optimizely's snippet, should go at the bottom of the page and be loaded 
asynchronously. 
 This approach is intended to ensure that even if these resources load slowly, they 
do not affect the user's visual experience.
 Optimizely works by changing the visual experience on the page as the site loads, 
making these changes before the visitor sees any content. 
FUNDAMENTALS OF PAGE RENDERS
The five fundamental strides of how a page renders are recorded beneath:
 DNS Lookup – finding the mentioned asset's web address (for example cdn.optimizely.com)
 Starting Connection – effectively conversing with that asset's location
 TTFB (time to first byte) – accepting the absolute first snippet of data from the asset (for example the 
principal snippet of data from Optimizely's CDN)
 Download/TTLB (time to last byte) – accepting the absolute last snippet of data from the asset, in this 
way enabling the asset to render outwardly (for example a picture) or execute (for example 
Optimizely's JavaScript bit can start its usefulness)
 Record Complete – the essential street sign that the site page has finished stacking the entirety of its 
assets
CDN OPTIMIZELY BALANCE
 Optimizely utilizes a Content Delivery Network (CDN), a system of web servers situated the 
world over, to give administration to the rendering the scrap as indicated by the means 
sketched out above.
 It is critical to take note of that Optimizely and its CDN just effect steps #3-5, since that is 
the point at which the solicitation for the scrap has arrived at the CDN. 
 Optimizely balances each solicitation so it can convey the bit to the guest's program from 
the physically nearest server and most elevated performing CDN. 
 This methodology enables the piece to stack as fast as conceivable in the program for 
whatever number demands as would be prudent, so that in any event, when stacking 
synchronously, Optimizely doesn't square different resources on the page. 
CDN OPTIMIZELY AND FLASHING
 Flashing, sometimes also called flickering, refers to when a page 
loads the original content for a short time before loading different 
content, creating a noticeable "flash" of the page.
 This can create a disruptive experience for website visitors and 
distract from the effectiveness of the content being tested. 
 Things to be considered when using Optimizely include: Placement 
on page, Synchronous versus Asynchronous Loading, Tag 
manager, and Snippet size.
IS CDN OPTIMIZELY BETTER?
 With BelugaCDN, which makes use of an IPV6 Network, you may be able to 
deliver 20-40% faster with its dual stack network.
 It can also provide real-time traffic statistics up-to-the-second so it is better 
than Github CDN in terms of updates. 
 You can also easily delete specific content from any location in just a click. 
 It is also user-friendly especially to developers who will most likely use this 
content delivery network. 
 It has advanced settings, fine control, and automation via a restful API. 
CONCLUSION
 BelugaCDN also has a myriad of tools to help secure and protect 
your content.
 It also works like the Amazon CloudFront or Stackpath but only 
costs a quarter of their prices which allows you to accelerate the 
delivery of your site’s content by using the power of a global 
cloud.
