The license for the commercial product contains a clause which prohibits disclosing benchmarks of their product without their written permission. (Heaven only knows why they would include such a clause.) My comment is not based on any formal benchmarks, but on the graphs produced by our monitoring of the production software under real loads, and on the query metrics from our middle tier software in the production environment. Even though it would be a huge stretch to call the comparison a benchmark under these conditions, this is a litigious society. I'm sure you understand my concern. Short of being compelled by law to open our records, I'm not comfortable providing any performance comparison which names the vendor. -Kevin
