Firebird and Multi Version Concurrency Control – why is so good

Spotted on dotnetfirebird blog
A nice white paper by Roman Rokytskyy that describes the multi version concurrency control system used in Firebird in comparison to IBM DB2 and Oracle 9i.

I found this quote on the Hibernate Tuning blog: [Ed:They linked to the Roman’s Page , Scroll down to “db2 and friends”]

In fact glaring are the benchmarks published by MySQL. I’d put to you that MVCC support is probably more important than a lot of other concerns in transactional computing (as opposed to batch processing and OLTAP type stuff)
