"Slowy is a tool which simulates custom connection's conditions and limits the network traffic to a specified destination port. It is created for web developers, like me, who need to test a website with a real-world connection, even on a local server. Slowy is an OSX MenuBar app, so it is lightweight and is placed only on the system topbar. "

Web developers using high amounts of domain sharding to work around low connection per host limits in old browser should reconsider their number of shards for newer browsers. Anything over 2 is probably too much, unless most of your user base is using older browsers.

Use this file to prevent your computer from connecting to selected internet hosts. This is an easy and effective way to protect you from many types of spyware, reduces bandwidth use, blocks certain pop-up traps, prevents user tracking by way of "web bugs" embedded in spam provides partial protection to IE from certain web-based exploits and blocks most advertising you would otherwise be subjected to on the  internet.

The advantage with WebSockets (over AJAX) is basically that there's less HTTP overhead. Once the connection has been established, all future message passing is over a socket rather than new HTTP request/response calls. So, you'd assume that WebSockets can send and receive much more messages per unit time.

Speed matters online. Study after study has shown that even 100 millisecond delays in load times negatively impact user experience and conversions. So it's no wonder that e-commerce experiences are particularly susceptible to performance as these recent bits of data illustrate. The average Internet connection speed around the world was 2.3 Mbps by the end of 2011.

Yottaa is proud to introduce Websitetest.com, a free testing tool with multivariate testing capability. In a single test, see how your website performs across multiple locations, browsers, and connectivity types. Set tests to run in the future at time increments of your choice.

SPDY is awesome. It's the first real upgrade to HTTP in 10+ years, it tackles high latency mobile networks performance issues and it makes the web more secure. SPDY is different than HTTP in many ways, but its primary value comes from being able to multiplex many requests/responses from client to server over a single (or few) TCP connections.

Nos navigateurs sont performants, ils savent gérer plusieurs téléchargements en parallèle. Ca nous permet de palier les serveurs lents, et d'optimiser le réseau. Le temps qu'on se connecte sur un serveur, qu'on fasse une requête DNS, le réseau reste occupé avec d'autres téléchargements.

At Opera, we love speed. We work hard to make our browser faster with features that speeds you up, but your connection may have a saying in how fast you can ...
