Perhaps traffic shaping is in use to reduce congestion and
ensure certain traffic has priority. My own firewall imposes
some limits on outgoing traffic which improved my upload
speeds from about 140kbit/s to above 250kbit/s. I believe my
ISP also uses such measures.
The other point is that internet routing is not always the
same for outgoing vs incoming traffic. I've not done this
recently but in the past I traced from my home system to my
remote account and back from my remote account to home. The
paths were significantly different.
