   > 10% performance penalty isn't wroth to be java compliance
   Where do you see a 10% performance penalty?
   Running a basic search using the SearchFiles demo project as a template (see #306) shows
virtually no impact in search speed and about a 1.5% increase in RAM usage.
   On the other hand, the IndexFiles benchmark has about a 4% decrease in performance and
a 23% increase in RAM consumption.
   Run your own benchmarks on 4.8.0-beta00012 vs 4.8.0-beta00011, I am interested to see if
you are getting different results.
   The problem here is that there seems to be a lot of focus on the *initial request* that
loads the `IConfiguration`, which is a single hit that happens once at startup. It is expensive,
but it doesn't happen during normal operation, you only notice it if you are continually stopping
and restarting the AppDomain.
   > in this case I strongly feels that move this to #IF TESTING is better option,
   you still have the whole functionality, you can run all the tests in release/debug and
get the same behavior.
   We just migrated from what is effectively that approach (using `System.Diagnostics.Debug.Assert()`).
Too many shortcomings to make it work effectively, and we were getting false positives as
a result. Not to mention, there are some test features that need to be *hard coded* to run
in production in order to make the tests work that aren't necessary in production. At least
with this feature, we can now turn them off.
   > but why should we stick to the java bad pattern implementation?
   I will tell you exactly why - unless we run all of the test conditions (and make no mistake
about it, the asserts are intended to be *test conditions*), we have no way of realistically
determining if the application is functioning correctly as it was designed.
