    jails Moving jail between computers with different CPU architectures

    I have a jail that I would like to run on different computers with different CPU architectures. For example, on one computer it is an old Intel Haswell, and on another it is an AMD EPYC 7003. First, this Jail is compiled from source on an AMD EPYC 7003 computer. Secondly, it contains many C++...

    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): 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...
