These flaws aggregated to website performance.<\/p>\n<p><b>Note<\/b>: Check your website performance, try these online free tools:<br \/>\n<a href=\"http:\/\/webpagetest.org\" rel=\"nofollow\">webpagetest.org<\/a> and <a href=\"http:\/\/gtmetrix.com\" rel=\"nofollow\">gtmetrix.com<\/a><\/p>\n<p>SPDY is incorporated with the objective of providing functionality that aids in resolving following:<\/p>\n<p><b>Scarce number of connections<\/b><br \/>\nThe approach through which HTTP is designed, it says that \u00a0each resource crave for a separate HTTP request to a server. On an average modern browser supports up to 6 concurrent connections with server. This shows if more than stated connections are required from the same server the browser will have to wait until one among the allocated resources has been downloaded before it can open another request. this phenomenon has significant effect on the page load time.<br \/>\nWith the advent of <a href=\"http:\/\/en.wikipedia.org\/wiki\/HTTP_pipelining\" rel=\"nofollow\">HTTP pipelining<\/a> \u00a0this problem was about to elope but it is still penalised with <a href=\"https:\/\/en.wikipedia.org\/wiki\/FIFO\" rel=\"nofollow\">First-In, First-Out<\/a> (FIFO) problem.<\/p>\n<p><b>Note:<\/b> Research accomplished by <a href=\"http:\/\/httparchive.org\/trends.php\" rel=\"nofollow\">HTTPArchive<\/a> shows that the average web page consists of 84 requests from 30 different domains.<\/p>\n<p><b>HTTP HEADERS<\/b><br \/>\nThe second issue in HTTP bucket is the use of uncompressed and unnecessary headers.<br \/>\n<a href=\"https:\/\/en.wikipedia.org\/wiki\/List_of_HTTP_header_fields\" rel=\"nofollow\">HTTP headers<\/a> serves as fundamental to web transactions work but all this has to be directed through wire and so more header you have, the longer request will take.<\/p>\n<p>Today&#8217;s technologies that compress the headers are usually optional. There exists still, the potential for compressing or emitting headers that are not required.<\/p>\n<p><b>Developer workarounds<\/b><br \/>\nWeb developers have strategically adopted numerous techniques to decrease load times. Few among them are:<\/p>\n<ul>\n<li><b>Image Sprinting<\/b>&#8211; Combining number of smaller images into one image \u2018sprite\u2019 and then using CSS to display the correct section of the sprite on the required page.<\/li>\n<li><b>Concatenation and minification<\/b>&#8211; \u00a0Combining multiple CSS or Js files in order to reduce the HTTP requests for a page. Whilst minification corresponds to the art of removing whitespace and other supplementary content within the files to reduce their size.<\/li>\n<li><b>Domain Sharding<\/b>&#8211; Putting the resource under sub-domains so that the browser can open more parallel connections.<\/li>\n<li><b>Inline Resources<\/b>&#8211; Using the Data URIs to embed the HTML code resulting in decreasing the number of HTTP requests.<\/li>\n<\/ul>\n<p>Since all these strategies are useful in escalating the load time still, they are very cumbersome to implement.<\/p>\n<p><b>Troubleshooting these with SPDY<\/b><br \/>\nLet us take a look of some of the features that SPDY aims to fix<\/p>\n<p><b>Multiplexed streams<\/b><br \/>\nSPDY accounts for unlimited concurrent streams over a single TCP Connection. Since the requests are interleaved on a single channel the efficiency turns out to be much higher in terms of fewer network connection, fewer but more densely packed , packets are issued.<\/p>\n<a href=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image01.png\"><img decoding=\"async\" loading=\"lazy\" class=\" wp-image-802 size-full aligncenter\" src=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image01.png\" alt=\"image01\" width=\"600\" height=\"371\" srcset=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image01.png 600w, https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image01-300x186.png 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a>\n<p style=\"text-align: center;\"><strong>Reducing Upload Bytes\u00a0<\/strong> <a href=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image02.png\"><img decoding=\"async\" loading=\"lazy\" class=\" wp-image-803 size-full aligncenter\" src=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image02.png\" alt=\"image02\" width=\"600\" height=\"371\" srcset=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image02.png 600w, https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image02-300x186.png 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p style=\"text-align: center;\"><strong>Reducing Download Bytes<\/strong><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image03.png\"><img decoding=\"async\" loading=\"lazy\" class=\" wp-image-804 size-full aligncenter\" src=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image03.png\" alt=\"image03\" width=\"600\" height=\"371\" srcset=\"https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image03.png 600w, https:\/\/www.ibeehosting.com\/blog\/wp-content\/uploads\/2015\/07\/image03-300x186.png 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p style=\"text-align: center;\"><b>Reducing Total Packets<\/b><\/p>\n<p><b>Request Prioritization<\/b><br \/>\nSPDY flow include prioritization.
