Does anyone know what kind of overhead is caused by enabling tracing in an
ASP.NET 1.1 app?
On my production servers I'd like to leave it enabled so I can view
trace.axd to get a feel for the activity and problems on my site, I'd leave
pageOutput="fal se". But I'm wondering what kind of extra load my servers
experience due to this. Any ideas?
I'm also curious how bumping up the requestLimit increases the overhead?
I'd like to use a value of 250 or more.
I haven't found any documentation on the overhead associated with tracing.

The performance hit is considerable, but it won't render the app unusable.
In fact, if your server fully loaded, I doubt the users would even notice.
I've done performance testing with and without tracing, and tracing cuts my
requests/sec in half, but my normal usage is way lower than my stress
testing usage, so I wouldn't worry. Because you are considering tracing in
production, I'm assuming that this isn't a "if the site is slow, we lose $5
billion" application. After your 250 request threshold is reached, the
performance will increase again because tracing will be turned off.

Performance on our site is definitely not the top concern, just the standard
'it should be reasonably fast'.
Thanks for the insight on your own performance testing.
I'm curious about your last comment. It was my understanding that the trace
request threshold was a rolling FIFO cache. You state that after 250
requests (assuming I set the limit at 250) it would stop tracing. Is this
true? I assumed it would just throw the top requests off the cache and keep
tracing. If what you're saying is true then the usefulness of it for me is
significantly reduced.

Yes, your fears are true. Test it out for yourself. Set the trace limit to
2, then hit your app. Only the first 2 requests will show up on trace.axd.
After the trace limit, it stops tracing.

Wow, that is hugely dissapointing. To me that severly limits the usefulness
of tracing.
I am surprised there isn't at least an option to enable it to act as a FIFO
cache.

Hallo,
The best thing would be to implement a trace call in every procedure to
write an entry in the log file:
If MySwitch.TraceVerbose() then trace.writeline("Procedure xyz started with
Parameters ...")
Unfortuantelly is this a lot of work.
Is there an easier way to implement a good tracing?
How is tracing done in professional applications?
Thanks, Thorsten

I'm trying to strike a balance between tracing detail and application
performance. Clearly, if I have an EventLogTraceListener or
TextWriterTraceListener activated, performance will degrade because of the
related IO.
However, if I have no trace listeners running (i.e. TraceListenerCollection
is empty, including removal of DefaultTraceListener) what is the performance
overhead since effectively Trace.WriteLine has no place to write?

I wrote a simple test program, console, that does one thing: log
DateTime.Now to a trace file.
I thought it would be lickety-split, but it's taking more than 10
minutes to write 1 million lines.
I looked at the trace and it's doing about 20 lines per second.
That's very slow.

This is what my supervisor is looking for.
We want runtime debugging/trace logging. In other words, we want to log
every method that was executed, perhaps the variables in it as well -
everytime the method is executed. This should be such that it can be
turned on/off in a configuration file.
This way it will help us locate the error exactly where it occured and
when and all variables related to it.

What is an overhead cost conneted with using the /d:TRACE switch?
The Trace class is a convenient and configurable logger, but it requires the
executable to be built with the /d:TRACE switch.
Is using of the switch heavy in terms of size and performance of the
executable? Is it better to write my own logger class if I want it to be
used in the release build?
