Suppose you don't want your Windows Apache2 server uploading more than 64 kB/s. Then follow these instructions:
2. Open C:\Program Files\Apache Software Foundation\Apache2.2\conf\httpd.conf with notepad.
3. Where you've got the big long list of LoadModule lines, add the following to the end:
LoadModule bw_module modules/mod_bw.dll
BandWidth all 65536
4. Save the edit and restart the server.
