Intel 82574L GbE LAN & MSI IM-945GSE-A


  • I succesfully installed pfsense 1.2.3 on the the MSI IM-945GSE-A with a dual Intel 82574L GbE LAN NIC. I have a 20/3 cable connection. I noticed extermely high latency (1400ms) when I am using e.g. uTorrent. On my Via C7 I didn't had this problem. When I enabled 'device polling' the latency stays constant under heavy load (12 ms) but the CPU is going to 100%

    Anyone else experienced this problem? Is it a driver issue with the 82574L ?

    Please help me out with this as it's driving me nuts..


  • Hi,

    I've got the same config here: IM-945GSE running 1.2.3 RC3 on a 100/10 cable conn.

    I just did a short test using Transmission on my MBP:

    Ubuntu ISO @90Mbps = some latency increase (test-ping went from 25ms to 60ms).
    Some other torrent @10Mbps down/5MBps up (about 3000 states) didn't really increase the latency.


  • Tnx for your reply. I discovered the cause of the problem. In the BIOS settings there is a APIC setting that could be version 1.0 / 2.0 or 3.0. For me the 1.0 setting works fine.
