Hello guys

Im trying to make a system, in C# .NET, that distribute market data to Excel sheets using RTD function.
But Im having performance problems to fire events to RTD.

When i fire about 900 events per second, the processor usage go to 100%, and this is very strange

This the COM Interop Interface code:

Code:
[Guid("6027F32B-9360-4615-9EFC-A6043806E64A")]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface BovespaEvents
{
    void UpdateNotify(string strategyname, string symbolname, string fieldname, float fieldvalue);
}

This is the method that I use the COM Interop Interface:

Code:
public void UpdateEvent(DataObject sender)
{
try
    {
        UpdateNotify(sender.strategy, sender.symbol, sender.field, sender.value);
    }
    catch (Exception err)
    {
        LogError("UpdateEvent", err.Message);
        if (err.InnerException != null)
        {
            LogError("UpdateEvent", err.InnerException.Message);
        }
    }
}
And this is the DataObject class:

Code:
public class DataObject
{
    public string strategy;
    public string symbol;
    public string field;
    public float value;

    ~DataObject()
    { 
    }
}
And I make an VB6 to consume this events, it could be a RTD

Code:
Private Sub myInteropClient_UpdateNotify(ByVal strategyname As String, ByVal symbolname As String, ByVal fieldname As String, ByVal fieldvalue As Single)
'
' code here
'
End Sub
Im stuck in this performance problem. Does anybody already see this problem before ?

Thanks Guys
