使用ESP32发布请求需要2秒

Question

我正在使用ESP 32将参数通过POST发送到网站，我正在使用此代码：

timeA=millis();
    USE_SERIAL.println(timeA - timeB);
    strTotURL=strBaseUrl+strPage;
    strTotURL.replace(" ", "");
    //USE_SERIAL.println(strTotURL);
    http.begin(strTotURL, ca); //HTTPS
    http.addHeader("Content-Type", "application/x-www-form-urlencoded", false, true);
    httpCode = http.POST(strParams);      
    if(httpCode > 0)         // httpCode will be negative on error
    {            
        if(httpCode == HTTP_CODE_OK) // file found at server
        {
            String payload = ">ADJ "+http.getString();
            USE_SERIAL.println(payload);//+payload
            timeA=millis();
            /*USE_SERIAL.print("time befor : " + timeB/1000);
            USE_SERIAL.print(" time after : " + timeA/1000);
            USE_SERIAL.println(" elapsed : " + ((timeA-timeB)/1000));*/
            USE_SERIAL.println(timeA - timeB);
        }
        else
        {
            String payload = http.getString();
            USE_SERIAL.println(String(">fail")+payload);              
        }
    }
    else
    {
       USE_SERIAL.print(String(">")+httpCode);
       USE_SERIAL.println(">Acc ER1");
    }

    http.end();

问题是该过程需要2秒钟的付出或付出（我测量了时间），有什么办法可以使它更快？
