What feature in Mozilla Firebird allows you to get downloads speeds upto 3x faster than IE6? I went to www.LinuxISO.org to download a version of Red Hat and was getting max speeds of 50\85kbps. I tried downloading the same file with Mozilla and no lie, I was hitting close to 300kbps consistantly. May have dropped as low as 225, but never under 200.

Has anyone else noticed such differences? Can anyone explain the differences.
