The performance results we got (3 to 4 orders of magnitude faster) were comparing against JDBC access with the database fully cached in RAM on the same machine as the client. Improving persistence IO with SSDs has no impact there. It is an architectural issue. Considering a perfect, most optimized, transparent OODBMS now: Even if IO was instantaneous, just the instrumentation for every single read and write access will have a significant toll.
