Sorry for using html mail just now, and thank you so much to Bob Vaughan for correcting me about this. This is the outlook version, hope this is not an html format again. :)
I am a fresh guy with net5501. The BIOS version of my net5501 is 1.33c. I have created an ubuntu 8.04 system for my net5501 board, with this instruction:
My net5501 works with both transcend 8G 133x FlashCard and Westdigital 160GB sata hard-drive. However, the write performance in both cf-card and hard-drive is poor. I tried to use "wget" to do a simple performance test. The test content is:
Transfer Protocol: FTP
Transfer application: wget
The other monitor application: top
Transfer file information: a 1GB size file
Server setting: no speed limitation.
At very beginning 2-3 seconds, the speed is about 10MB/s, then, it just fall to 1-2MB/s. And during this whole progress, the speed is not stable (from 900KB/s to 6MB/s), the average speed for this progress is about 1.6MB/s.
no more than 5% (get by "top")
At very beginning, I just used a trancend 8G 133x CF, and I considered that the poor performance come from the CF card. However, with the westdigital 160GB sata hard-disk, the performance is almost the same. I guess there are some problem with my net5501 or my operating system.
Would you please help me to solve this issue. Thank you so much.
