Hi Diego,
are writing about the line
string ss = msg.ToString();
?
Can I ask you what's the goal of this conversion?
Thanks a lot,
Lanfranco

Subject: {{Quickfixn}} Message.ToString() Performance
Hi,
Using this code
Int idorden = 10500;
while (true)
{
string msgqueve = "8=FIXT.1.1_9=279_35=D_34=15_49=MAEFIXSORClient1_52=20200901-18:28:59.224_56=MAEFIXSORServerDesa_11=48212_15=ARS_38=1000000_40=2_44=15_54=2_55=AY24D_59=1_60=20200901-18:28:59.223_63=1_110=50000_126=20200901-18:28:59.150_432=20200901_5682=BON1_453=2_448=20949931030_447=C_452=3_448=RC2_447=C_452=1_10=089_";
Message msg = CreateMessageFromFIXString(msgqueve, SessionId);(function create message from string not added for space in email)
Stopwatch stopWatch = new Stopwatch();
stopWatch.Start();
for (int i = 1;i< 2000000;i++)
{
DateTime inicio = DateTime.Now;
idorden++;
msg.SetField(new QuickFix.Fields.StringField(11, idorden.ToString()));
string ss = msg.ToString();
DateTime fin = DateTime.Now;
if ((fin - inicio).TotalMilliseconds > 0.5)
Console.WriteLine("str ="+ (fin - inicio).TotalMilliseconds);
//Session.SendToTarget(msg, SessionId);
}
stopWatch.Stop();
TimeSpan ts = stopWatch.Elapsed;
// Format and display the TimeSpan value.
string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
ts.Hours, ts.Minutes, ts.Seconds,
ts.Milliseconds / 10);
Console.WriteLine("RunTime " + elapsedTime+ "yime "+DateTime.Now.Ticks);
System.Threading.Thread.Sleep(900);
}
I have noticed a random performance drop in the transformation of the message.
I have not been able to attribute it to the internal lock of ToString ().
Could you help me evaluate the best way to transform to string?
Regards,
Sergio Diego Demaestri
