A capable 200 lines profiler. It features a very simple API, supports multiple threads and dumps to a profile in the Trace Event Format

• Keep in mind profile.zig has hard limits like max_frames and max_threads, this is done to cap the memory usage, you can increase or decrese them as nescesary to your project.
• Use profile_file.zig to reduce memory usage and record as many frames as you want, is still limited max_threads
• Uses rdtsc instruction for better measurements like tracy, this adds a 200ms startup delay nescessary to peform an initial timer calibration, it's also possible to get an illegal instruction if you CPU doesn't support it
• Inspect traces with Perfetto

const P = if (enable_profiling) @import("profiler.zig") else @import("profiler_mock.zig");

pub fn main() !void {
    P.init(.{});
    defer {
        P.dump("profile.json") catch |err| log.err("profile dump failed: {}", .{err});
        P.deinit();
    }

    const zone = P.begin(@src(), "main_fn");
    defer zone.end();

    // ... your code
