Re: GUI extreme slowness due to log4net

Many thanks Wayne - it sounds like mine is the opposite in that within
VisualStudio 2005 it works fine but not within the GUI.  However I shall
look at those links you sent.

 

Cheers...Di

Hi Di,

 

I'm not sure if this is related but the words "bad performance" and
"NUnit GUI" strike a chord for me, so it's potentially worth a shot! Not
too long ago we ran into very slow NUnit GUI performance after we
upgraded our code base to VS2005. Running in the NUnit console was more
or less unaffected. (I'm not sure about the NUnit integration with
VS2005 since I have never yet tried it. (We have licenses for
TestDriven.NET, but I personally like to see those green lights in the
NUnit GUI :-)

 

Anyway, back to the point; we did some research into the performance
issue that we encountered and found that our particular performance
issue is caused by VS2005 itself.

 

One of the developers that did this particular piece of research pointed
us to these links.

 

General Debugger Performance Info:

MDA Performance Problem:

x
http://blogs.msdn.com/tlai/archive/2006/06/15/How-to-Disable-a-Specific-
MDA.aspx

 

After reading and absorbing the above, we decided that internally the
best use for us was to use the environment variable approach. "To
disable MDAs via an environment variable, define an environment variable
named COMPLUS_MDA and set it equal to 0." Note that this also requires a
reboot.

 

After doing this the performance of the NUnit GUI was back to the
performance levels we had experienced in previous versions under VS2003
and also now consistent between the NUnit GUI and console.

 

Hopefully this information helps, but if not I wish you all the best in
trying to resolve your performance issue.

 

Regards,

Wayne Hartell.

	Hi

	When I run the tests within visual studio, they run very quickly
but within the GUI they are EXTREMELY slow.  This seems to be due to the
fact that all DEBUG messages are still being generated and  captured not
filtered even if my default App.config does have them set to INFO.  Can
you suggest how to fix this in the GUI?

	 

	Thanks...Di
