DFU over CDC ACM very slow

Hello

I am doing a bluetooth dongle and I added MCUBOOT with CDC ACM to be able to update my app. 

I find that the update takes a lot : 5+ min to update a 200kB application.

This is questionning me because I have an other bluetooth product with a nRF52840 too and I can do an update within 30s max by ble.

It would seem logic that USB dfu is faster than BLE.

    What do I have to do so my application can support command ./nrfutil device x-boot-mode-get --traits mcuBoot

    Please not that my application support the retention boot mode. I am able to reset in mcuBoot through a function in my app but I need an external event to trtigger my function. Being able to do it via nrfutil would be a monumental improvement for my application.

    Regards
