I somehow have a hard time believing that you can feel the performance of the tcp stack while browsing of all things in a VM, are you sure it can be attributed to that?

Yes, I also have same hard time believing in it, but internet felt snappier.

Sounds more likely that your OS just had less things going on and your browser not as many extensions running as your daily driver browser.

FreeBSD 4.x was considered by many as the most stable FreeBSD ever. Mainly because there were 11 point releases of fixes and enhancements (4.11), as opposed to today where FreeBSD major version only have 3-4 point releases. https://www.freebsd.org/releases/

Likely also by comparison to FreeBSD 5 directly after it, which introduced concurrent kernel entry (instead of a single giant lock) and was considered somewhat buggy for a while. Or so I am told.

It was not only the most stable, but for many applications, especially in networking, it was also the fastest single-threaded operating system, beating easily Linux and Windows XP or 2000.

FreeBSD 4 wasn't too bad on dual cpu systems, as I recall. Fine grained locking gets more important as cpu counts grow, of course, but at 2, the single Giant lock isn't unreasonable.

No, not really. I have many old Linux VMs too, with different degree of rot, and FreeBSD has noticeable smaller tcp connection establishment latency. Youtube opens way faster than on both older and newer linux vms.

It was the tcp stack. Only possible reason.

I had this experience recently and realised I had crippled my day to day system with a slow DNS resolver. Suddenly everything was snappy.

Huh...may need to check.

I never looked into the release history, but I ran a server with 4.10 for 8 or 9 years and never felt the need to upgrade it.

That's also the period Yahoo and other companies had a tremendous investment in FreeBSD. FreeBSD is great on its own, and that amount of attention also meant every single bit of performance would be extracted no matter what it takes, and any scaling or stability issues would be hammered out pretty quick. Until they moved to redhat...

> Until they moved to redhat... Does anybody know why they switched to RedHat ?

I always assumed money, but I'd love to know as well.

I've only ever lost data on Linux ext* filesystems, never on FreeBSD UFS or ZFS. 20 years ago it was unfortunately not unusual to experience the Linux "nuclear fsck" where it scrolls by so fast and for so long you know it's toast.

I've 100% had issues with UFS, it's a simple filesystem and subsceptible to corruption. ZFS meanwhile is a different beast altogether which is designed to ensure data integrity at all costs.
