Hi all,
I am using 3Com 3CBLSG48, it is a 48 Port 1Gbps Switch ...
And using Two W2K3 R2 x64 with DFS/DFS-R as File Server on HP ML350 G5 Server with 1Gbps LAN Card build-in
I am using AMP Cat 6 UDP LAN Cable too.
While I am using Win7 RC copy some big ISO File (480MB) from the W2K3 R2 to my Win7 Desktop, it max just can 30MB/s ...
I am wonder why a 1Gbps LAN just 30MB/s? How to speed it up
Thank you very much.
之前我也遇到相同的問題,也有發問過,我系統為 Vista 兩台電腦互傳資料,大概區網最高傳輸都只有5MB〈Vista 傳檔時顯示的數字〉,我找資料將 TCP/IP v6 關閉,如下面機碼
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
"DisabledComponents"=dword:000000ff
再將Qos關小一點,如下面機碼
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched]
"NonBestEffortLimit"=dword:00000005
區網傳輸速度可以提升到15~25MB不等
不知道對你有沒有用,試試看吧!
File Server上的硬碟配置?
Please check your harddisk's speed.Use some software like "HD Tune(http://www.hdtune.com/)".
If your harddisk speed's average is 50MB/s.When you transfer file,the max speed limit is 50MB/s.
client的新舊(i.e. GbE接在PCI或PCI-E上)?? 防毒關了沒?? BTW,用網芳在GbE上拉檔案效果通常不會太好,建議用FTP試試,再者如果server/client間只有switch(L2)而非router(L3)的話開了jumbo frame有很大的機會是不work的(router對IP做fragment/defragment時除了payload外,IP header也得處理過),因為L2 switch或許可以把GbE上的jumbo frame fragment/defragment成100base上最長1500byte的Ethernet封包,但L2的設備對L3是無能為力的,所以IP header部份很可能會出問題....
Just use windows performance counter to display the disk drive's performance.
I bet, In such case, the drive of the desktop is the bottleneck.
You can try another way to test --- do a local copy --- copy the same file Win7 locally and Win2003 locally, and post the result here, too.
可以試試用iperf一類的軟體,先測試一般狀態下,兩台電腦之間的大約頻寬能到多少
就像很多人都有測過,iperf在GB網路上,配上不太差的硬體,兩臺電腦之間可以壓搾出900Mb以上的頻寬
不過,網芳傳檔,卻很少能超過50MB...
