I think it is normal result.  

If you do the same test, you will find the upload will be much faster than download.

I ported lwip1.4.1 to my system. And I added a simple ftp server in my system.
It simply uses a RAM disk as filesystem. When I tested it with Windows ftp, I got
about 6MB/s for upload(put), and 3Mb/s for download(get).
Why there is so great difference and how to speed up.
Does lwip send data after tcp_write?
