STm32 ST-Link Utility Frequency Settings

One can set different frequency from Target -> Settings -> port.
Does this frequency settings effect the speed of user application or just  for the speed of flash programming via SWD?
And how to understand the info from ST-Link below.

If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.

In my application running at 40MHz for STM32F091, most of boards are loading Flash via SWD at 1.8M, but few had to use lower frequency to connect to target and program the flash. Does this mean those Chips using lower frequency for programming has some default?

Thanks.
