No dobra, po epokowej przerwie (ostatnio wpis jakieś 4 lata temu?!!) mam coś ciekawego.
Szybki up-to-date, wkręciłem się w nowego „dotneta” (.NET core) a ściślej ASP.NET Core.
Jak zwykle przeglądając czeluście internetu trafiłem tutaj: https://caleblloyd.com/software/net-core-mvc-thread-pool-vs-async/
Wiedziałem że słowo kluczowe async, await w programowaniu usług sieciowych w C# musi mieć jakiś większy sens i treść i oto wytłumaczenie. No więc nie byłbym sobą gdybym nie zmaścił jakiegoś benchmarka. Postanowiłem za autorem użyć podobnego scenariusza i przetestować metody (kod ASP.NET core WebAPI):
// GET api/values/sleep
[HttpGet("sleep")]
public string GetSleep()
{
Thread.Sleep(1000);
return Process.GetCurrentProcess().Threads.Count.ToString();
}
// GET api/values/delay
[HttpGet("delay")]
async public Task<string> GetDelay()
{
await Task.Delay(1000);
return Process.GetCurrentProcess().Threads.Count.ToString();
}
No i dobra, ale przydałby się jakiś kod testowy C# a nie odwołanie (jak caleblloyd) do pakietu stress-testującego. No to wymyśliłem takie coś (fragment kodu aplikacji GUI):
private async Task SyncAcynsWebProcessing(CancellationToken token, int seconds2Run = 60, int threadCount = 50)
{
Stopwatch watch = new Stopwatch(), global_watch = new Stopwatch();
int run_times = 0;
string url = txtDebug.Text.Trim().Split(new[] { '\r', '\n' }).FirstOrDefault();
global_watch.Start();
while (true)
{
if (!token.IsCancellationRequested &&
global_watch.ElapsedMilliseconds > (seconds2Run * 1000))//do this procedure X number of seconds
break;
var all_tasks = new Task<int>[threadCount];
watch.Reset();
watch.Start();
for (int i = 0; i < threadCount; i++)//create-and-run x tasks
{
all_tasks[i] = Task.Run(async () =>
{
try
{
using (var client = new HttpClient())
{
var stackContent = await client.GetAsync(url, token);
var response = await stackContent.Content.ReadAsStringAsync();
if (response.Length > 10)
{
return response.Length;
}
else
{
if (int.TryParse(response, out int j))
return j;
return -1;
}
}
}
catch (Exception ex)
{
this.Dispatcher.Invoke(() =>//run something on UI thread
{
txtDebug.AppendText(ex.ToString());
});
return -2;
}
}, token);
}
//wait for all threads to complete
await Task.WhenAll(all_tasks).ContinueWith((all_results) =>
{
watch.Stop();
this.Dispatcher.Invoke(() =>//run something on UI thread
{
string comm = "";
txtDebug.AppendText(Environment.NewLine);
foreach (var res in all_results.Result)
{
txtDebug.AppendText(comm + res);
comm = ",";
}
txtDebug.AppendText($"{Environment.NewLine}ElapsedMilliseconds: {watch.ElapsedMilliseconds}");
});
watch.Reset();
foreach (Task<int> tsk in all_tasks) tsk.Dispose();
all_tasks = null;
}, token);
//await Task.Delay(250).ConfigureAwait(false);
run_times++;
}
this.Dispatcher.Invoke(() =>//run something on UI thread
{
txtDebug.AppendText($"{Environment.NewLine}----------{Environment.NewLine}Bottom line summary: {global_watch.ElapsedMilliseconds}"
+ $" run {run_times} times");
});
}
To cudo wykonuje przez zadaną ilość sekund (domyślnie 60) działanie polegające na zasypywaniem serwera wielu króciutkich zapytań i sumuje odpowiedzi (które są ilością sumą wątków robocznych .NET). Robione jest to specjalnie przez X sekund i z zadaną ilością wątków (domyślnie 50) aby równo obciążyć (czyt. dobić) serwer.
