Re: [microblaze-uclinux] Error when processing wget

["Qichen Huang" <huangqichen@xxxxxxxx>]

I have tried the uclinux/microblaze running at 100 MHz on Virtex 4 as
well. It has the same problem.
It sometimes failed to complete download process. The speed is quite
unstable and is not faster than 10mbps ethernet.
Here is the result of my measurement:
using 100MHz uclinux/microblaze (ML403, virtex4):
10mbps, top speed 843KB/s, average speed to download a file (2 or 10
Mbyte) varies from 330KB/s to 775KB/s.
100mbps, top speed 820KB/s, ave. speed varies from 294KB/s to 682KB/s.

I don't what has caused this problem.

regards,
Qichen
