How Nexedi moved to HTTP2 with Caddy

After trying and failing to move to HTTP2 using Apache in 2017, Nexedi has adopted Go language based Caddy server. Initial results of HTTP2 show significant speed improvement and good stability. Next step will be the adoption of QUIC. Migration was smooth and entirely automated thank to a test driver devops approach recently introduced in SlapOS.

Edge Computing for Industrial Automation and Control

The business of industrial automation and control will move away over time from existing, highly profitable, proprietary product lines towards much more flexible yet less profitable open hardware and Free Software. Future profits will eventually emerge from online services based on industrial big data, personalisation, legal regulation and trade secret powered by increasingly smart sensors and gateways at the edge.

A multi-core Python HTTP server (much) faster than Go (spoiler: Cython)

A multi-core Python HTTP server that is about 40% to 110% faster than Go can be built by relying on the Cython language and LWAN C library. A proof of concept validates the possibility of high performance system programming in the Cython language.

Python mulit-core benchmark in uvloop context

The existence of cython combined with a clean concurrency model based on technologies such as gevent and pygolang could change the situation if both can be tightly integrated into cython's static cdef code rather than scattered as it is today.

Optimising MariaDB for Big Data

MariaDB is used at the core of ERP5 and Wendelin. Thanks to NEO distributed object store, MariaDB can store hundred terabyte of big data information such as wind turbine vibration, noise, server logs, etc. We explain in this blog how we currently optimise MariaDB to obtain good results and what remains to be done at the core of MariaDB to reach even further scalability.

High Peformance Multi-core Python at Nexedi

Nexedi has been able to use python language in a multi-core high performance fashion for over 10 years. We explain how in this blog and provide a simple set of rules to quickly remember how and why python is suitable for concurrent programming. We also explain our decision to use golang in rare cases where python is not suitable.
