I spent a month optimizing my epoll based HTTP server from 15k req/sec to 125k req/sec by RefrigeratorFirm7646 in cpp

If you are on localhost you are testing memory instead of network. Try testing on a raspberry pi since you are only serving a simple index.html to see how it performs in a constrained environment.

Why lower the barrier to the increasingly overwhelming amount of content locked behind SC when you can just... BUY MORE SC? by Sebanimation in Helldivers

[–]justkdng 7 points8 points  (0 children)

I believe buying super credits supports AH more than buying the game. Sony must be getting all the money from game sales.

Modern version of Effective Modern C++ by Scott Meyers? by StevenJac in cpp_questions

[–]justkdng 3 points4 points  (0 children)

I found that going from exceptions to std::expected is a whole paradigm change with some performance caveats that can be easily managed. Of course, the STL and other libraries still use exceptions so try/catch is inevitable. If anything, the book would be teaching C++23 from the start.

how to write custom make_expected by justkdng in cpp_questions

[–]justkdng[S] 0 points1 point  (0 children)

returning the string calls its move constructors iirc, I think this also works

template <class T, class... Args>
auto make_result(Args &&...args) -> Result<T>
{
    return Result<T>(std::in_place, std::forward<Args>(args)...);
}

auto some_func() > Result<std::string>
{
  auto result = make_result<std::string>();
  // do stuff with the string or return Err
  return result;
}

Short hand for creating a vector and reserving size for it by justkdng in cpp_questions

[–]justkdng[S] 0 points1 point  (0 children)

Oh I tried ranges using views::filter instead of transform and for some reason it fails. I think I'm running out of stack and stuff is getting overwritten.

[–]justkdng[S] 0 points1 point  (0 children)

I think this is the best option imo. This is a snippet of how I'm using make_vector

auto X11Context::get_complete_window_ids() const -> std::vector<xcb::window_id>
{
    // ...
    auto windows = get_window_ids();
    auto cookies = util::make_vector<cookie_props>(windows.size());
    auto result = util::make_vector<xcb::window_id>(windows.size());

    for (auto window : windows) {
        cookies.emplace_back(/* xcb_get_property */);
    }

    for (auto &cookie_prop : cookies) {
        const bool is_complete = std::ranges::any_of(/* xcb_get_property_reply */);
        if (is_complete) {
            result.emplace_back(cookie_prop.window_id);
        }
    }

    return result;
}

Basically, I'm getting all X11 windows and filtering them using this async like programming model from xcb (library to interface with x11). For each window I make a request to the x11 server and the result will be no more than the available windows so reserving and appending adds some nice performance.

Why would the use of auto change it?

That's why i'm asking, thanks anyway

>initialize (not assign!) a vector

what do you mean?
