Challenges of Outperforming Interpreters with JIT Compilers on Modern CPUs
By

Slow-proofed and worth the wait. Worth its weight in flour.
Summary
The author discusses the challenges of creating a JIT compiler for PostgreSQL that can outperform a well-written interpreter on modern CPUs. The article explores why beating interpreters is more difficult than commonly assumed, examines CPU architecture considerations, and outlines potential optimization strategies for both the JIT compiler and the interpreter itself.
Key quotes
· 3 pulledI am often asking myself how to really beat the interpreter... And on 'modern' CPUs, with a well written interpreter, that's far more complicated than many would imagine.
So in order to explain all this and show how I am planning to improve performance (possibly of the interpreter itself too, thus making this endeavor self-defeating).
Since my previous blog entry about JIT compiler for PostgreSQL, sadly not much happened due to a lack of time, but still some things were done.
