Hi,
I can see TCP retransmission happens during files upload and download process time to time.
I am using Keil Middelware Network component to Put and get FTP files.
It is very very slow.
My total RAM is 128kb
I am currently using default TCP settings on keil.
As I understood FTP uses TCP.
1) Middleware version : Network version : 7.0.0.0 , FileSystem : 6.6.0 (We did not upgrade to latest FileSystem pack. We will try with latest pack updated soon.
2) Average Upload transfer speed = 31k/s and average Download transfer speed = 88k/s 3) upload is slower. 4) We use NOR Flash with Embedded File system.
5 ) I saw another issue. If I use two network connections on my Windows 7 machine. I used second network connection low priority ( I think) to connect to to my embedded device. basically I have two network interfaces on my windows 7 machine then FTP put and get will be more slower. I saw FTP connection is more slower.
Thanks, Naeem
I guess I use HTTP put to send file . I will still face same issue. because underlying cause is TCP transmission is slow.
If any solution let me know. Is it related with out device only have 128 KB RAM.
Potential slow TCP performance in Network version 7 has already been corrected. If you are using an FTP client, slow TCP performance might affect your application too. Please ask support for the updated libraries.
