Getting started

A few basic examples can be found in the Examples/ directory.

Debug vs. Release builds

The Debug build depends on log4net and has log4net calls in some of its classes and code paths.

The Release build does NOT depend on log4net and, taking advantage of conditional method attributes, does not include any calls to log4net methods. This ensures that there is no performance impact on release builds.

Performance benchmarks

The Test/ directory contains a few benchmarks that were used to guide the design and implementation of Packet.Net. These benchmarks either contain 'performance' or 'benchmark' in their names.

If you have a performance concern or issue you'll want to write a concise test that reproduces your usage case in a controlled manner. It will then be possible to run and re-run this test case in various profiling modes in order to look at potential ways of optimizing code. The tests will also provide a baseline from which to compare any proposed performance improvements in order to ensure that changes are not inadvertantly reducing instead of increasing performance.
