Excellent advice! I thought it was "Download the Mall" at first, then
realized it's "Download Them All!"  I'm hitting 603.5KB/s  !! Thanks

Just about every time I'd download something from cisco it would want to
take forever. I use FF with downloadthemall now and destroy Cisco's
bandwidth. I'm sure they're not happy about it, so it's a good thing I
don't do it often.

You can try taking the download URL and changing it to rtp- 

download.cisco.com.  I'm not sure if this still works but it used to.

Anyone else notice the sj-download.cisco.com is slow?

 

 

 

Second try at downloading 7.1.2a, first try the file sizes were too  

small and checksum didn't match;

Why is cisco.com so slow? I downloaded FireFox 3.5 at 3MB/Sec, and  

VMWare Workstation 6.5 at 1MB/Sec.  I have a 8MB Cable Modem.

 

 

 

Second try is a failure too....
