StarProbe Performance

We performed a number of experiments to test speed of StarProbe. The result indicates how StarProbe can work on large datasets.

System

The following system was used in the experiments;

• Hardware: Sony Vaio Laptop
• CPU: 1.6GHz Pentium 4
• Memory: 512MB
• OS: Windows XP
• Java Runtime: JRE 1.4.2 (Sun Microsystems)

Data

The data used was as follows;

• Records: 1 million records
• Fields: 13 fields (6 categorical, 7 numerical)

Performance

The result of the experiments are as follows. Note that it does not include I/O since the data used was well compressed by StarProbe and OS was able to cache all of them!
