    Increasing wifi throughput


      We're developing a product using the BCM94343W connected to an ST32F4 MCU over the SDIO interface, and we're having trouble achieving a high data throughput when publishing messages using MQTT. We're using WICED 6.2, ThreadX v5.8, with NetXDuo v5.10_sp3. The SDIO interface is running at its max speed, and even with the MCU running at 100MHz the best throughput we're able to achieve is only around 40-50 kilobytes/second. I've seen posts on this forum about upload rates in the vicinity of megabytes/second, so just wondering if there are any settings in the WICED network stack or elsewhere that I can take a look at to debug this.
