This helps to minimise locking allowing multiple sessions to access the same data at the same time. On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute. To benchmark a database we introduce the concept of a Virtual User. The Python GIL.

Last week we saw the benefits of rethinking memory and pointer models at the hardware level when it came to object storage and compression ( Zippads ). The protections are hardware implemented and cannot be forged in software. And this all has to work for whole-system executions, not just the C-language portion of user processes.
