TMG 2010 SP2 with Rollup 3 slow download/upload speed

    Question

  • Hi,

    I have Service Pack 2 with roll-up update 3. The download speed is constantly limited to 5 Mbps and the upload speed is limited to 1 Mbps. If I use an alternative gateway (Linux), I constantly get 20 Mbps download and 20 Mbps upload

    I have turned off Malware Inspection and applied all suggested registry solution plus the script to increase TCP buffer but to no success.

    The TMG server (Windows 2008 R2) is installed as a Hyper-V 2012 guest. The alternative gateway (CentOS) is also installed as a Hyper-V 2012 guest. Both are hosted on the same Hyper-V 2012 host. Both are also connected to the same dedicated physical NIC.

    Any help would be greatly appreciated.
