Anyone have any information about FTP transfer rates on K6x family?

[mscovel]

We have RTCS, FTP and MFS running on a 180 MHz K65 with KSDK 1.3 (MQX).

We are finding FTP transfer rates around 14 K bytes//sec which seems slower than it should be.

We have removed all code except the above (commented out our application) and find that the best speed we can achieve is ~30 K bytes/sec.

Has anyone ever seen FTP performance rates above that on ANY K6x CPU?

Knowing what other have achieved will help us know if we have a problem we can fix.

Any help is much appreciated!

I don't have any server numbers, but I have a 96 MHz K64F client sending to a PC-based server at well over 100 KByte/sec. That rate with the server on the same 100 Mbit/sec subnet as the K64F client. This on a "classic" MQX 4.2 BSP-based implementation rather than KSDK. Data are sourced from either an SD card or a 1-bit wide SPI flash ROM, both bound to MFS.

Thank you very much Fred. Are you using RTCS or lwip or other? What FTP (embedded and PC app)?

[fcw]

Using RTCS.

Servers are Bulletproof FTP and Filezilla. 

The client is a fair amount of application code around the client functions documented in the RTCS reference manual.

Hi Mark:

Is your board running as a server or as a client?

Our board is a server

Thanks
