基本上網卡跟硬碟是關鍵....

剛好之前有做實際Test.
Acer小狗機 <-> IBM T41 (Broadcom <-> Intel 1000MT Mobile??) 以Cat5E直連約600Mb
Acer小狗機 <-> HP NC4010 (Broadcom <-> Broadcom) 以Cat5E直連約420Mb
Giga Switch hub有接沒接都差不多
以上為iperf測試,時間為一小時平均值
看看這周末來不來得及玩到Intel 1000MT Server adapter...(之前買了一塊,結果有問題..)
這樣就能配合另一臺有Giga網卡的(好像是Marvell的)同時在某臺Giga switch hub亂鬥 XD
(當然,絕對不是CISCO...也不是Dlink..是更便宜的ASUS,而且好像造成Intel網卡合併工作上有問題..)
另外題外話,在用iperf測試時,我的小狗機CPU Loading是100%,IBM T41則只有60%上下...
不論誰是Server或Client端..(就看著小狗機CPU溫度高到82度C....)

記得BCM跑Gigabit蠻慘的....
排名可能比螃蟹還後面....

CPU使用率高也不足為奇了

囧rz
看來BCM5705M(HP NC4010)跟BCM5788(Acer 3002WTMi)都是降低成本後的結果
沒關係,比硬碟寫入速度快就好

Dear all:

今天剛裝好一台新Desktop，上頭有內建 Gigabit 網路介面，就隨手拿 iperf 測試了一下，有興趣的可以參考一下。

Desktop 上網路chip 用的是 Intel 82566DM 晶片
Server 上網路 chip 用的是 Marcell Yukon 88E8056 晶片

網路線是前年鋪的，應該只有 CAT.5 (可能連5e都不是)；
中間經過兩個 SWITCH，都是 DLINK 的；另外 Server <-> Client 走線大概有10~20m 距離

參數 iperf -c 192.168.0.9 -i 60 -t 120 -P 10

cat.5的線只能有100M的傳輸速度.......這樣的結果也是可想而知

9xMbps是單一connection的throughput,樓上的網友開了10個connection,所以總throughput是9xxMbps ....BTW,如果Cat5的線/接頭品質沒有問題的話(主要是要真有4對線而非只有兩對線),短時間拿Cat5測出來的throughput其實和Cat5e是差不了多少,只是長期而言就沒人有把握了....

用cat6應該會好一點
