I have to admit that it is very convenient to assume that users will all get broadband eventually. And I, like many developers, fail to remember that we tend to have much faster connection speeds than many of our users. A common pitfall of Flash design is to allow a fast connection to lull you into a false sense of usability for your content. My office has a lightly loaded fibre optic connection which is virtually 10 times faster than even what DSL users are experiencing.
So what can be done to test Flash for 56k modem users when you enjoy such a high-speed connection? I started using a product called CCProxy about six months ago, and it has been not only useful, but free! The product is an Internet sharing proxy that is free for up to 3 users, which is 2 more than I need. Best of all, you can set the allowable bandwith. When I want to see what modem users will experience, I set the bandwith to 7,168 bytes/second. I also need to tell my browser to proxy through port 808. If I need to switch back to full speed, I just turn off the browser’s proxy option.
My only complaint, and it is a minor one, is that you must calculate the bytes/second in order to get the bandwith setting you need. I have a cheat sheet that I keep handy just for this purpose however. If my calculations are correct, here are some common connection speeds, and the appropriate bandwidth setting:
- 56k modem = 7,168 bytes/sec
- 128k DSL = 16,384 bytes/sec
- 256k DSL = 32,768 bytes/sec
- 512k DSL = 65,536 bytes/sec
- 1m Cable = 131,072 bytes/sec
