    Just want to validate myself.
    The client has just upgraded a 10M service to a 70M service.
    However – no matter what we do, we can’t seem to exceed more than about 250KB/sec download speed in a single IE session (plus, the director keeps telling me it’s “slow”)

    If I run multiple IE download sessions, I can get 8-10 sessions going with 200+KB/sec for each instance, but cannot seem to find a single source I could download from to demonstrate the speed will max out. and a speedtest specific to the IP generally don’t show more than 10M/sec download either.

    I’m wondering if, somehow, there’s something wrong in my admittedly very plain and boring config below. If any QoS or something would help out?

    Yep – that’s really it. I know that’s very poor firewall control – but one step at a time.

    There’s only data going over this network, no voice. The internal fabric is a bunch of SF300s, (Fast Ethernet, 100Mb/sec) switches, with a single flat vlan, connected with Gigabit uplinks between the switches and the router.

    there’s about 70 seats within the network at the moment.

    anything else that might help paint a picture, let me know :)
