Running the simple hello world code below takes an average of 8 seconds to execute (200 samples, Minimum 64ms, max 14 seconds using jmeter).
I do not see app stops in the logs so why so long and why such a variance?
Note I've tried from multiple network connections, internal and external so doesn't appear network related.
public static class Function1
{
[FunctionName("Function1")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello Universe, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}
}
Log file doesn't show anything unusual:
