how much the HTTP transfer rate can archive on esp32

hi guys, i have a question here.
May i know the httpd transmission rate on WiFi transmission is how much, either TCP and UDP.

i'm using the FTP(file transfer protocol) on esp-idf. but the download file speed is extremely slow, below 1MB/s.
I need to transfer the chunk files in 5MB.

DuerOS 加上录音功能

想问一下,esp32-lyrat 接入 DuerOS 有了对话功能之后,还是否可以进行录音?
