My app is a client connected to a server. It has its own socket class

run loop calls NSStreamEventHasBytesAvailable. I parse this data line
by line and output it with NSLog(); A simple case statement causes all
kinds of things in my app to happen. No problems. However, the problem
I am running into is if I want to display the raw data to the user of
the app in a NSTextView.
In high volume times 10+ lines a second can came across. The GUI of my
app lags and there is nothing I have been able to do to stop it. I
have tried putting the text directly into the textStorage I have tried
replaceCharactersInRange:withString: I tried writing the data out to a
text file and then reading it back into the NSTextView.
Do you have any advice on how to print this data to the user without
it lagging my GUI? Do I need a separate thread?
How about not updating the text view every time the data comes in, but
limit updates to say once or twice a second?
