The best ultra-accelerator for servers and web pages that powers up with any connection.

After cached VCLServer UltraCDN occasionally multiplies the useful bandwidth by MORE THAN A THOUSAND, while caching is somewhat lower than without VCLServer. A beta version is currently being offered (in trials) and the definitive version is expected to be released later this year. All connection types have not been checked; At least 512Kbps of upload speed is recommended. Calculations are approximate and non-contractual. To demonstrate power this page is running agile thanks to only one server with VCLServer UltraCDN and a WiMax connection of 1Mbps of upload.

VCLServer: servers grows, pages are ultra-accelerated.

VCLServer is a software that reduces the bandwidth needs of your PHP / MySQL server in a way that increases its performance to professional levels while multiplying the speed of the pages.

Images, videos and almost any other type of files that does not require processing of your server, VCLServer UltraCDN upload them on external servers located in different places of the world that you can choose, thus bringing them to user concentrations to increase the speed of the pages.

This greatly reduces the bandwidth needs of your server and also reduces the needs for access to the hard disk, increasing the physical performance and increasing the number of users to be able to service without additional hardware.

Test of performance.

Performing tests with a page that hosts 1,277,456 bytes, of which 1,273,268 are videos and images and 4,188 bytes are PHP and CSS files, when using VCLServer UltraCDN to cache videos and images the results indicate that needs of bandwidth and disk are reduced by 99.67%:

1.273.268 / 1.277.456 x 100 = 99.67%.
Through a blog that also contains images and videos we have been able to verify that there were 35,000 visits per day without reaching the full bandwidth, allowing more than 1,000,000 monthly visits with a connection of 1Mbps without saturations.

Through a page of test of 3MB with files of different sizes and the free test of loadimpact.com that simulates the progressive increase of users, we see that with VCLServer Ultra does not have any impact on page performance even with the maximum number of users and multiplies by 300 page display speed.
