Perofrmans test error

[AhmetNuri]

hello, I did a performance test on a new horse server that sent 100,000 requests in a row and measures the time of the incoming replies, but it gave an error after 17000 records.
this test
I also did it on indy rest server, MARS Rest server, Datasnap RestServer, mORMot Rest Server. All other vehicles successfully completed the test. Is there any additional setting you think I need to do?

What kind of application did you create? Console? Could you put the code here?

var
i : integer;
sw: TStopwatch;
oldWorking, kacak: Integer;
Satir: TStringList;
ResultStr: string;
begin
Memo1.Lines.Add('Start Test :' ;
ResultStr := '';
kacak := 0;
Satir := TStringList.Create;
sw := TStopwatch.Create;
sw.Reset;
sw.Start;
oldWorking := -1;
// RESTClient1.BaseURL := 'http://127.0.0.1:8080/rest/default/HelloWorld';
Memo1.Lines.Add('Hourse Indy Test');
try
for I := 1 to 100000 do
begin
if ResultStr = '' then
begin
try
ResultStr := IndyRequest(HourseURL);
finally

    Satir.Add(ResultStr);
    ResultStr := '';
    Application.ProcessMessages;
  end;

end
else
begin
  Application.ProcessMessages;
  kacak := kacak + 1;
end;

end;
except on E: Exception do
Memo1.Lines.Add(e.Message + ' ' + i.ToString)
end;
sw.Stop;
Memo1.Lines.Add('Respone Count :' + Satir.Count.ToString);
Memo1.Lines.Add('Wait Count :' + kacak.ToString);
Memo1.Lines.Add('Time(ms) :' + sw.ElapsedMilliseconds.ToString);
Memo1.Lines.Add('END :' + TimeToStr(Now));

Hello,
these days I am also testing the performance of Horse ... I use Apache Benchmark tool to do the tests.
https://httpd.apache.org/docs/2.4/programs/ab.html

My server is an Ubuntu 20.04 (4vCPU and 8gb Ram) with Docker + NGINX + SSL (Let's Encrypt) and Horse in reverse proxy.

I hid my data with xxxxxxxxxxx

I tried from another server to call Horse like this:
ab -c1000 -n100000 https: // xxxxxxxxxxxxx / ping
and the server return a simple json response
requesting 100,000 requests with 1000 simultaneous calls.

this is the result: ... there are 205 failed but it was a nginx ssl issue

Apache has too many external parameters.
which makes it difficult to compare between libraries.
I prepared my own test environment for it. Everything is the same except the libraries used are different
