You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.
I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is
This is a list of general-purpose optimizations for C programs, from the most impactful to the tiniest low-level micro-optimizations to squeeze out every last bit of performance. It is meant to be read top-down as a checklist, with each item being a potential optimization to consider. Everything is in order of speed gain.
Choose the best algorithm and data structure for the problem at hand by evaluating:
This is for a used Wyse 5070 I recently purchased, having the J5005 CPU and a huge 8 GB RAM all running on AlmaLinux 9.1. Why AlmaLinux? Because I'm partial to RHEL-based systems with its focus on stability, that's all. Unfortunately the downside is that oftentimes new software isn't readily available.
I want to unlock the ability to perform hardware-accelerated transcoding in ffmpeg so I can use it in Tdarr as a decent remote transcoding node.
Intel ARK - Pentium Silver J5005 shows that the CPU has Quick Sync Video support, and as such supports some form of hardware video acceleration.
The CPU is Gemini Lake and uses Intel UHD Graphics 605, which is Gen 9.5 according to the ffmpeg wiki. The machine should be able

This explains how to build mesa from source, and how to use the custom built mesa to run some apps and games, without needing to replace the mesa libraries that your operating system runs on.
Let's assume that you are using an x86_64 system.
