昨天也用iperf測了一下PCI和PCI-E的差別


iperf版本1.7.0(新的找不到windows下的)


一端是桌機內建Marvell 88E8056，OS是WinXP SP3

另一端是Core Duo MODT電腦，OS跑FreeBSD 6
內建Intel 82573L Intel PRO/1000 PL Network Adaptor (應該是走PCI-E的)
另外插一張Intel Pro 1000/GT在PCI

Switch是ASUS GigaX 1108M (之前很便宜的那台GbE switch)

網路線是雜牌Cat 6


server端參數 iperf -s -w 65536



Marvell 88E8056 -> Intel Pro 1000/GT (PCI)

不過實際檔案傳輸都差不了太多，好像是都卡在硬碟IO，
所以最多衝到5~60MB/sec而已。
