[Mono-winforms-list] Too slow performance on RichTextBox?

[sharkal]

Hi,

i am listening on some udp ports at the same time, where messages will be
received asynchronous in average ~ each 5-10ms. These messages i will write
into a logfile at a lower level ( own thread)  and also display the message
in the GUI in a RichTextBox with a certain color. For this, i add the
messages in a list  and a backgroundworker will flush the list after a
certain period into the RichTextBox:
                rtxtLogMessages.SuspendLayout();
                foreach (var log in logMessages)
                {
                    rtxtLogMessages.AppendText(log.Value + "\n");
                } 
                rtxtLogMessages.ResumeLayout(true);

*The problem is*, that displaying the text takes too long time. If i receive
messages in an interval around 25ms, then it is fast enough.
I heard, that it is possible to change any low-level settings of mono to
have a better performance. Does anyone has an idea, how to do or what i have
to do  to solve the problem?
In Windows, the performance is fast enough.
