I think my internet speed is very slow. What's a good way to test actual modem performance? Do you know about any benchmark software for modem ?

file downloads are a good way to test modem performance. The trick is to make sure you're really testing the modem's raw transfer rate, and not some other factor that you're not aware of. Here are some guidelines for download

Use an FTP program. Web browsers often lie about download rates. FTP is more reliable. Note that some FTP programs reports download speeds in Kilobits per second (Kbps), while others use Kilobytes per second (KBps). To convert, multiply Kilobytes per second by 10 (eight bits plus the start bit and stop bit). Download a pre-compressed .zip file. If the file you download isn't compressed, hardware data compression in the modem will kick in, leading to erroneous results. Different file types compress to different degrees. Use .zip files for your tests.
Download a file that's at least 200 K. A file size of at least 200 K will minimise the effects of TCP/IP slow start. Ideally, download from your ISP's server-the closest server to your modem. To eliminate congestion issues, download early in the morning or late at night.
