CDNvideo: Acceleration of the websites

The CDNvideo company – operator of a content delivery network (CDN) in Russia and the CIS countries – announced at the beginning of 2013 the beginning of providing the innovation service "Acceleration of the Websites" for acceleration of work of the websites which sharply increases the speed of opening of pages of websites, eliminating one of the reasons of leaving main today visitors from them. The service of CDNvideo company integrates the technologies of complex optimization of web pages accelerating their creation and display with content delivery on CDN network. Such integration distinguishes service of CDNvideo from all services of acceleration of the websites presented at the Russian market and increases effect by 30%. The Acceleration of the Websites service is of paramount interest to Online stores and any organizations which actively apply e-commerce provide content to the wide mass of Russian-speaking users or highly appreciate the image. At the same time in most cases return of investments (ROI) takes less than a month.

It is known that the speed of opening of pages of the Website and its response to actions of users makes the defining impact on their behavior. According to Google and Amazon.com, each 0.1 sec. of a delay when opening the page of the website leads to decrease in attendance of the website by 4% and to lowering of sales for 1%.

It is known also that increase in response time of the page from 2 for 38% increases the probability that the user will leave it to 10 sec., having crossed out thereby all efforts of the owner of the website on its creation, information filling and promotion.

Now the Russian companies spend very considerable funds for a saytostroyeniye, however results are far from ideal. So, according to the research of Runet conducted by CDNvideo together with partners for the last year the best indicators showed the websites of insurance companies. Here unacceptably slow (the page opens in eight and more seconds) were only 7% of the websites, and for 48% of the websites of the page no more than four seconds open. In the banking sector similar indicators it is much worse (18% and 30%, respectively). And absolutely badly the situation is in Online stores (33% and 11%), i.e. in business where the website is the main instrument of sales and communications with clients. Actually here only every tenth website meets the basic requirements of "usability", and every third will inevitably cause irritation – even if all its other characteristics (from quality of information to the working schedule, the mode of delivery, the range and the prices) are at the top level.

The service of CDNvideo increases the speed of loading of the websites by 70%. It means that its application is capable to solve a speed problem for the vast majority of the websites, and not only in the specified industries, but also in scales of all Runet. Besides, for 10-15% the general failure ratio of the website goes down, and the failures connected with slow loading decrease by 90%. Besides, this solution unloads server resources, increases performance and reliability of the website at the moments of peak loads and influx of visitors, improves its provision in search systems. Let's especially note that conversion of visits in sales increases by 5-40%.

Speed of opening of the website depends on a set of the reasons. Long time limiting factors were: performance and loading of the Web server and data sources, real capacity of the channel of connection of the server to trunk section of the Internet, inefficient routing of traffic and also bandwidth and type of "last mile". A few years ago the importance of these factors sharply decreased – as a result of growth of power of DPCs of providers, development of infrastructure of Runet, wide circulation of broadband access and emergence in Russia of commercial CDN. To the first places there were delays connected with creation, caching and display of difficult web pages and also using numerous static elements, including very volume multimedia - audio-and video this. These delays save the importance and now. However today, the role of factors of the first wave – in connection with rapid increase in popularity of the mobile Internet raised again.

The service optimization block "Acceleration of the websites" reduces delays by imposition, delivery and drawing of web pages. Here are applied: the improved compression of the text and images, the consolidation CSS-and JavaScript-files, the postponed loading of frames and styles, post-loading of JavaScript blocks, simplification of CSS rules, reduction of complexity of an object model of documents (DOM) and also specific optimization, the drawings of the HTML-code leading to acceleration in that browser in which the user works (all modern browsers are supported). All these conversions are executed automatically. There are also additional particularly complex methods of acceleration of the HTML-code which require work of highly qualified specialists, but give an additional gain of speed for 10-20%.

Connecting service for the specific website, specialists of CDNvideo install on it the easy proxying application which either buffers an information stream, or receives it through API of a management system for the website, and then issues the optimized HTML-code equivalent to end users. This application supports all versions of a PHP environment and practically all widespread content management systems (CMS). Static web objects of the website are automatically cached on servers of distribution of a content delivery network CDNvideo and these copies used when processing the subsequent addresses. Such architecture does service in acceleration of the websites absolutely transparent for users and practically does not create load of the server. The permanent account in CDN network and technical support is provided to the owner of the website.
