FreeRTOS LWIP connection is slow

Hi, is there any update on this? I also see the similar kind of speed issues. Surprisingly if I start the application from the flash (.ldr), communication is super fast. Something strange happening when the application is started in CCES (2.9.2) with Emulator.

Hi, we are not aware of any issues with performance. We will take a look into this.

One thing to check is that you have set up the debug session correctly for use with FreeRTOS.

FreeRTOS uses the SWI interrupt, which is also used by the printf system. The debugger latches onto these SWI interrupts and looks for an IO message each time. The result is that it can considerably slow down the execution of applications under CCES.

If you take a look at the FreeRTOS User Guide, section 3.1.4, this will explain how to disable the semihosting support.

Please let us know if this makes a difference.
