                Performance testing different Key-Value stores in Ruby
              
          
    For a project I am on I need to use a key-value store to converts file-paths to fixnum IDs. The dataset will typically be in the range of 100 000 to 1 000 000. These tests use 305 000 file paths to fixnum IDs.
The Different Key-Value stores tested are:
Daybreak: "Daybreak is a simple and very fast key value store for ruby"
GDBM: GNU dbm. "a simple database engine for storing key-value pairs on disk."
DBM: "The DBM class provides a wrapper to a Unix-style dbm or Database Manager library"
PStore: "PStore implements a file based persistence mechanism based on a Hash. "
Out of these, all except Daybreak are in the Ruby standard library.
