Google has just released Page Speed, a tool for Firefox/Firebug. It lists all factors on a page that could cause unnecessary download lags for users.
Features covered include gzip compression, browser caching, using efficient CSS selectors (the less descendants the better) and the need to minify Javascript.
As broadband penetration is now over 95% in the UK these sort of factors only seriously come into play when designing a high traffic website and potentially high bandwidth costs have to be a consideration. If you are in east London then visit Stratford web design for all your digital needs.
What’s so attracting about this little tool is that previously it was used by in-house Google technicians and developers, so its usefulness is assured.
Previously I used the Web Page Analyzer, but I’ll be using Page Speed too from here on in.
