I was discussing this patch with Andres. He's not very keen on my
densehash hash table idea and suggested that instead of relying on
trying to make the hash table iteration faster, why don't we
Hi,
cfbot now runs most tests on windows, the windows task is by far the slowest,
and the task limitted most in concurrency [2]. Running tap tests is the
biggest part of that. This is a bigger issue on windows because we don't have
infrastructure (yet) to run tests in parallel.
There's a few test

INTENTION
Inspired by the effort to integrate JIT for executor acceleration I thought
selected simple algorithms working with array-oriented data should be
drastically accelerated by using SIMD instructions on modern hardware.
I want to introduce this style of programming with the example of he

Hi,
Currently the server is erroring out when unable to remove/parse a
