Have tried booting the system off of another distro's live cd (Fedora,
Ubuntu, etc...) to see what kind of download speeds you get from
those. I very highly doubt this is a general linux issue, more likely
an issue with something in your gentoo setup, but the live cd could
help prove this point.
Also, what software are you using to download on both OS's? what
protocol are you using? While this likely isn't a filesystem I/O issue
you could always try directing your download output to /dev/null to
see if that helps too.
