Slow performance on Windows 10

[davechurchill]

I can install and compile your code very easily, but for some reason a simple GET to a localhost server takes upwards of 20 seconds, whereas it is instant in firefox. Is there a Windows firewall setting or something that may be causing this?

Im also having a really slow binary execution.
I'm using it to send data to influxdb 2 REST API. The data arrival with this library works just fine and appears in influxdb immediately. But the program keeps stuck and doesnt print any response after ~ 20-30 seconds. I think its the buffering of the response? Is there any way to skip response buffering?

Here is the code that I use:

#include "include/HTTPRequest.hpp"
#include <iostream>
#include <chrono>
#include <string>


int main() {
    try {
        http::Request request{"http://ip.to.influxdb.server:8086/api/v2/write?org=roboflex&bucket=roboflex-test1&precision=ns"};

        float pseudo_measurement = 49.77;
        long long t = std::chrono::time_point_cast<std::chrono::nanoseconds>(std::chrono::system_clock::now()).time_since_epoch().count();

        std::string lineprotocol = "testmeasurement,pseudotag=pseudo1 test_percent=";
        lineprotocol += std::to_string(pseudo_measurement);
        lineprotocol += " ";
        lineprotocol += std::to_string(t);

        const auto response = request.send("POST", lineprotocol, {
            "Authorization: Token MyInfluxdbToken",
            "Content-Type: text/plain; charset=utf-8",
            "Accept: application/json"
        });
        std::cout << std::string{response.body.begin(), response.body.end()} << '\n';
    }
    catch (const std::exception& e) {
        std::cerr << "Request failed, error: " << e.what() << '\n';
    }
    

    return EXIT_SUCCESS;
}

Here is the time it took for execution:

EDIT:
If I pass a delay to the send method with chrono the execution of the binary is fast and the data arrives just fine although there is an error that is thrown:
Request failed, error: Request timed out
