mORMot 2 ORM Performance

By Arnaud Bouchez, 2022-02-15. Open Source › mORMot Framework

The official release of mORMot 2 is around the edge. It may be the occasion to show some data persistence performance numbers, in respect to mORMot 1.

For the version 2 of our framework, its ORM feature has been enhanced and tuned in several aspects: REST routing optimization, ORM/JSON serialization, and in-memory and SQL engines tuning. Numbers are talking. You could compare with any other solution, and compile and run the tests by yourself for both framework, and see how it goes on your own computer or server.
In a nutshell, we almost reach 1 million inserts per second on SQLite3, and are above the million inserts in our in-memory engine. Reading speed is 1.2 million and 1.7 million respectively. From the object to the storage, and back. And forcing AES-CTR encryption on disk almost don't change anything. Now we are talking.

EKON 25 Slides

By Arnaud Bouchez, 2021-11-16. Open Source › mORMot Framework

EKON 25 at Düsseldorf was a great conference (konference?).

At last, a physical gathering of Delphi developers, mostly from Germany, but also from Europe - and even some from USA! No more virtual meetings, which may trigger the well known 'Abstract Error' on modern pascal coders.
There were some happy FPC users too - as I am now.

I have published the slides of my conferences, mostly about mORMot 2.
By the way, I wish we would be able to release officially mORMot 2 in December, before Christmas. I think it starts to be stabilized and already known to be used on production. We expect no more breaking change in the next weeks.

OpenSSL 1.1.1 Support for mORMot 2

By Arnaud Bouchez, 2021-02-22. Open Source › mORMot Framework

Why OpenSSL? OpenSSL is the reference library for cryptography and secure TLS/HTTPS communication. It is part of most Linux/BSD systems, and covers a lot of use cases and algorithms. Even if it had some vulnerabilities in the past, it has been audited and validated for business use. Some algorithms […]

Fastest AES-PRNG, AES-CTR and AES-GCM Delphi implementation

By Arnaud Bouchez, 2021-02-13. Open Source › mORMot Framework

Last week, I committed new ASM implementations of our AES-PRNG, AES-CTR and AES-GCM for mORMot 2.
They handle eight 128-bit at once in an interleaved fashion, as permitted by the CTR chaining mode. The aes-ni opcodes (aesenc aesenclast) are used for AES process, and the GMAC of the AES-GCM mode is computed using the pclmulqdq opcode.

Resulting performance is amazing: on my simple Core i3, I reach 2.6 GB/s for aes-128-ctr, and 1.5 GB/s for aes-128-gcm for instance - the first being actually faster than OpenSSL!
