This directory has some benchmark scripts and their results.

Benchmarked libraries

I tried to include all ruby directories monitors which use Win32 API that I know of. If there are more, please let me know about them.

• WDM
• FChange
• em-dir-watcher

Usage

1. Run bundle install to install all the prerequisites.
2. Each type of benchmark is stored inside a separate directory. To run a benchmark, go into the directory of the benchmark and run the benchmark.rb file.

Results

Here are the results of the benchmarks which were gathered on an Intel Core 2 Duo machine running Windows 7 (64-bit):

Impact on performance

From the previous results you can conclude that FChange and WDM are the obvious winners. Thus, this test didn't include em-dir-watcher.

• FChange: 65216,47%.
• WDM: 41,13%.
