PCI gigabit NIC limited by processor?

[mc866]

Here is a retest with my pc as the server and WHS as the client:

Two oddities from your last results -- (1) the performance has gone up significantly. What changed? (2) The "-r" still isn't working -- we should see two sets of results in one test.

Going on, can you provide some more information on the server and the PC?

- motherboard, processor, RAM, OS, NIC, drive configuration, percent free, file transfer details (file sizes, transfer method and direction).

Here is a log with my HTPC as the client and the WHS as the server, looks to be much better, I'm guessing my issue may be my workstation then

More info.

Going off my theory that my onboard NIC in my main PC may be the issue I took one of my cheap Gig NIC's and put it in there. Here are the results.

[Emulex]

you did disable all firewall related software/nac ?

 

[mc866]

I did not no,

 

[Emulex]

yeh disable the firewall(s).

microsoft firewall service
any other firewall services

not disable the firewall; the SERVICE behind it.

i have SEP 11 RU5 on some machines; it's anti-network attack whatever adds like 10ms to each ping (well not that much). I guess it inserts a driver to sniff all packets and long and triangulate attack vector if an outbreak occurs. it indeed causes lag and slowdown.
