I don't know why but IE nearly always has problems downloading files from Cakewalk, right back to at least Sonar 8. I suspect (from previous threads about this) that the problem may be more pronounced if you're in the UK (or maybe simply outside the USA). It's not just a matter of time but corrupted downloads as well.
IE8/9 (tried both) announced that the complete download would take well over 48 hours, and hung after 3 hours.
Firefox downloaded the files (haven't tried running them yet though, so don't know if they are corrupted or not), with no problem other than taking about 3 times the usual download time for that much data. Sensible explanations a-plenty for that kind of time increase, but not for the IE one. My guess is an IE bug of some sort.
I routinely transfer files in excess of 1GB, and the only sites I have ever found where IE routinely slows to a crawl on file download are Cakewalks. Ditto the corrupted downloads problem. The missing file extensions people are reporting after downloading with IE is
another problem.
Traceroute to the file server indicates no apparent problems with intermediate hops, and IE and Firefox are using the same route.
