Repeatable Measurement

Metrology is "the science of measurement" (wikipedia article). So ergalic metrology is the science of measuring computational tools. International Bureau of Weights and Measures (BIPM) defines metrology as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology."

This project's goal is to understand how one can get repeatable measurements with little variance of CPU time and I/O, which are surprisingly difficult problems, and then how to measure DBMS activity accurately. It turns out that even simple interactions with a DBMS exhibit wide variance in time.

The result is the TTPv2 protocol.
