The number of objects in the average web page has reached triple digits. In just under 4 years, the number of objects in the average top 1000 web page has doubled from 49.9 objects in January 2009 to 100 objects in November 2012 (see Figure 1). By the end of the year, the average top 1000 web page is on track to break 100 objects per page.
The average web page is now over 1MB in size, with each of its various components increasing in file size as well (HTTPArchive.org June 2012). PDFs can become so large that some email programs and gateways will not allow them to pass (with 5MB or 10MB file size limits). This article shows how you can efficiently split your PDF into multiple files to fit within the 5-10MB email gateway limits.
Although 80% of web performance problems are typically due to front-end issues (Souders 2009), back-end bottlenecks can slow your site down to a crawl. One thing to watch out for is when static pages load relatively quickly, while dynamic pages load slowly. This article shows what to look for when a server slows down a web site.
JPEGmini is image optimization technology that reduces the size of JPEGs by up to 5 or 6 times their original size, while maintaining resolution and perceived quality. Developed by ICTV, an Israeli startup company, JPEGmini works within the existing JPEG standard to optimize the size of JPEGs for faster downloads and lower storage costs. The patented algorithm developed by ICVT allows JPEGmini to compress images just below the level where perceived artifacts appear. The results, as you will see below, are smaller files that look visually identical to the original images. In this article we test the new service, and interview the CTO.
I’m back from my combined business and hiking trip out west, visiting the Velocity 2011 Web Performance Conference in Santa Clara, California. The second part of my trip was devoted to hiking and photography in the great Northwest, which we won’t review here. This year’s Velocity was bigger and better and yes, sold out again. Here are some highlights.
Page Speed Online is a web-based version of the Page Speed plugin, that allows developers to analyze web pages without the need of downloading an extension. Page Speed Online also features a mobile page analysis, which lets developers analyze their mobile sites like they are viewed in a mobile browser, with mobile-specific optimization recommendations. This article shows the new free service in action.
