| PGO Build Results ( Sept 20th, 2008 )

The program loads 15,000 random records from a text file into 4 tables each using a different method for storage and searching.
- Simple Table: Uses an array and a linear search.
- Chain Table: Uses an array of link lists. Search is done with a Hash Key.
- Hash Table: Uses an array and searches with linear probing. Also uses a Hash Key.
- Tree Table: Uses a binary search tree.
After the data is loaded into a table, 30 different tests are run against it. The same 30 tests for each table.
Here are the Results.
