this is already the third time github actions is down this week at wednesday morning

Estonia is also a really good choice within EU. With their digital residency card, everything can be managed online with digital signatures only.

this is very naive reimplentation of the C# version. I managed to reduce the runtime of the same file from 5.7 seconds to just 800ms

    using var file = File.OpenRead("file.bin");
    var counter = 0;
    var sw = Stopwatch.StartNew();
    var buf = new byte[4096];
    while (file.Read(buf,0,buf.Length) > 0)
    {
        foreach (var t in buf)
        {
            if (t == '1')
            {
                counter++;
            }
        }
    }

    sw.Stop();
    Console.WriteLine($"Counted {counter:N0} 1s in {sw.Elapsed.TotalMilliseconds:N4} milliseconds");

You just need to do File.OpenRead instead of OpenText to get a FileStream, then you can read the buffer

but it makes function calls, it's not neglectable as it's called as many time as the bytes the file has

most of the latency comes from network layer. my naiive guess is they probably switched from a standard ethernet setup to a infiniband setup to achieve 600us of total latency.

Even the status page is down for me. Please don't host your status page in same network/domain.
