Wonderful tool that act as proxy between your web browser and your computer’s internet connection. It allows you to see lots of info regarding page loading, script and flash optimization.
One of its greatest features is the ability to simulate a dial-up connection.
Differently of other simulators, which append directly to your network interface and saw your connection from time to time to simulate low speeds, this is a proxy: it receives all the data normally from the web server, and then streams it to your browser, not only giving a real speed, but latency as well — a HUGE difference when you got to do synthetic tests.
Best of all: it’s made in Java, which means it’s cross platform. Works like a charm on both OS X and Windows, and Linux, for you geeks out there! :)
I’ll definitely buy this one.
