This document describes an experiment testing the performance of a main-memory database using physical memory as primary storage and disk as backup. Various tests were run involving 1,000 transactions across 80 database extents, with the transactions consisting of either 1 operation or 1-5 operations. The tests varied the percentage of updates versus queries from 0% to 98% updates. Metrics like transaction throughput, wait times, and deadlocks were measured. The results showed transaction waits and deadlocks increased with higher percentages of updates, while throughput was promising at over 200 transactions per second for single-operation transactions.
