Page Speed Service 15 years ago
Absolutely great. What do people await? It is a free service helps to improve ya site. I run the g-pagespeedtest + webpagetest and received a list with errors in my project http://www.webdesign-angebote.com Especially pics and js made problems.
And the suggestions are okay, really helpful {background-color: expression(this.runtimeStyle.backgoundColor = 'none'} and "Compress Images", but thats been my fault. I adepted it immediatly and hope for improved user- and rankingresults.
