How CDN Optimizely Can Help to Improve Your Business?
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.
However, Optimizely works by changing the visual experience on the page as the site loads, making these changes before the visitor sees any content. When customers implement the Optimizely snippet synchronously and in the head tag, the snippet can execute its changes before the content loads, and customers experience a minimal increase in page load speed. Primarily, there are two ways that Optimizely can affect the load speed: latency and flashing.
CDN Optimizely And How Latency Affects Load Speed
Latency alludes to when a page is delayed loading or render. This is effectively perceptible when a website page sets aside a long effort to show in a program, pictures gradually show up, or the webpage's textual styles and styles set aside a long effort to apply to content. Website pages load through a progression of steps as the program demands and gets all the different assets that make up that page (pictures, CSS documents, JavaScript records, and so on.). 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
How Does CDN Optimizely Affect the Steps to Be Taken?
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.

Optimizely progressively load-balances between the two quickest and most generally utilized CDNs on the planet, Akamai and EdgeCast. This makes the full circle as a component of TTFB shorter, and comes to TTLB sooner, so Optimizely can make changes on the site that any longer before Document Complete. This methodology significantly diminishes reaction times for 99% of site guests, and enables clients to amplify the ROI from tests
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 Than BelugaCDN?
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. 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.
