    Jails vs Docker performance

    I recently came across research (Bachelors thesis) that benchmarked jails against Docker. The conclusion was that, except for startup time, Docker outperformed jails in almost every category (memory - writes/sec, IO, CPU - events/sec). In some categories (read from disk), Docker outperforms by...

    Is there an operating system faster than FreeBSD for the Maze Solver benchmark?

    I think I did the 'Maze Resolver' test correctly. This is my result with a 10 year old dual-core CPU: Phoronix results with the 3970X (more recent 32 core CPU): https://www.phoronix.com/review/chrome-80-benchmarks/4 Phoronix results with the 5950X (new 16 core CPU)...

    Solved net/samba413 encryption, security/gnutls on Aarch64

    Hello. It seems security/gnutls from ports and pkg are not making use of the AES acceleration features from the ARMv8 Cryptographic extensions. This makes Samba server encryption incredibly slow. I've observed this on a Mac M1 FreeBSD 13-RELEASE virtual machine and also a RockPro64 running...
