ftp performance issues over WiFi

 

Hi All,

We are using the TI Sitara AM37X Evaluation Module (EVM) Sitara (Win CE 6.0 R3)from Mistral for developing a handheld device

 TI WL1271 module is interfaced to the hardware for WiFi functionality.The performance tests for testing the file transfer functionality for a file download from laptop to EVM shows pathetic performance  .

The throughput is approximately 1-2Mbps .However iperf shows good throughput(18Mbps). Please let me know if anyone has observed this behavior.

The results repeats if tested on a wired network (eth interface of EVM) .Also the same ftp application and test setup works with good throughput on a competitor platform(EVM replaced)

 

Thanks,

Jithendran
