Why is there no BSDCNC?

Obviously, we have LinuxCNC, designed for Debian with some real-time stuff.

However, I have installled FreeBSD and its derivatives (GhostBSD) on several computers and have noticed that it is very fast, efficient, and low-latency.

It is almost devoid of stupid useless background processes (Linux is pretty good too, though I suppose Windows has lowered the bar so low at this point by adding ads to the login screen and stuff).

Why is Linux the favoured OS for stuff like this?

As an added bonus, BSD-CNC rhymes!

By what metric have you been testing latency ? Your process and figures would be interesting to see.

The other thing that would be a major obstacle is that there is no real time kernel for BSD in the way that there is for Linux. Syscalls maybe another issue as well, I'm unsure whether the APIs for BSD and Linux are the same.

Linuxcnc isn't "designed for debian" originally the ISO were built for Ubuntu, but licensing became an issue. Linuxcnc can be built for any distro. Years ago I was running Linuxcnc on Slackware and in a moment of pure madness I built it on a system built using the LFS & BLFS way.

As for "stupid back ground processes" it's up to the user what they want to run in the background and what features they want to lose. Do you want the OS to mount a drive when plugged in or do you want to mount & umount the drive manually ? What processes do you sugeest turning off for the best system ?

Most of us don't have 96GB of ram though.

I am partial to the FireWire 800 on my 2011 iMac.

In Ubuntu, there's a SUPER annyoing bug that causes the whole File program to break sometimes when you eject a disk without unmounting it first.

You must click "unmount", then "eject", or it might just stall; a pain.

Not sure why, but Linux seems to copy files to USB eys wayfaster than Windows or even Mac (admittedly, the Mac coputers i use are from 2011 so not really a fair comparison), especially for USB 3 thunderbolt drives.

When I say "low latency", Ijust mean everything feels 2x faster.

Installing a package with pkg is almost instant, much faster than with stupid apt (it let me down a few to many times for me to fogive it).

The network speed is really good (for ethernet, never tried Wi-Fi); ping latency is absurdly low.

I can test on my FreeBSD server on Monday.

I can test on my GhostBSD laptop tonight.

How would you like me to test latency?

The BSD latency command (preinstalled on Mac!)?

You are forgetting one thing. Linuxcnc is based on Linux and depends on the Linux preempt_rt kernel to provide a real time thread (the servo thread).  To use a different OS like  BSD or RTEMS, you will need to rebuild a large amount of the Linuxcnc application not to mention the huge number of dependencies that are prerequisites.

Latency has nothing to do with speed.

You're the one that made the claims, yet you've done no testing nor do know understand the concept of latency. There seems to be a disconnect between what you actually know and what you think you know. The thing is you don't get it. I don't think you ever will, it would be some much better if you just fucked off and stopped wasting peoples time of the forum by having to clear up the bullshit you post.

A lot of stuff does work well on FreeBSD, if unreliably.

What always makes me mad is that most software available on "all platforms" isn't available for FreeBSD, or any other BSD for that matter.

In what sense is something available for "All Platforms" if FreeBSD is not supported?
