Improved remote protocol

From Dmitry Yemanov – The remote protocol has been slightly improved to perform better in slow networks. In order to achieve this, more advanced packets batching is now performed, also there are some buffer transmission optimizations. In a real world test scenario, these changes showed about 50% less API roundtrips, thus causing about 40% less TCP roundtrips. Hopefully, this is an improvement some our users could benefit from (mostly it should affect over-the-internet database access).

This work has been committed into the HEAD branch to be included into the next Firebird version. Further protocol improvements are also planned.

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)
