"The contrast with Docker is striking: while the Docker container required 100% CPU to reach peak for the HTTP and HTTPS throughput, the FreeBSD jail delivered the same speed with ~60% of the CPU sitting idle. In terms of performance cost per request, Jails are drastically cheaper."
I clearly wrote that the tests I performed in the latest blog post are 'with a default configuration, without optimizations'.
In many places where the link is circulating: 'You should have enabled XYZ and ZYX!'
Another data corruption, fortunately not fatal, with btrfs. Two mirrored disks that have little activity. On the same server, Proxmox 9, there is also a ZFS pool (mirrored, more active). Same type of disks.
An employee mistakenly connected an electric heater to a socket protected by the UPS, and the server rebooted brutally.
Upon reboot, one of the two btrfs disks reported:
[ 167.015266] BTRFS error (device sdd): parent transid verify failed on 873906176 wanted 998679 found 998677
[ 167.017007] BTRFS error (device sdd): parent transid verify failed on 873906176 wanted 998679 found 998677
[ 167.052517] BTRFS error (device sdd): open_ctree failed mount: /btrfs: can't read superblock on /dev/sdd.
Result: unable to mount, even in degraded mode. The only way was to disconnect sdd and mount the other disk in degraded mode.
No issues with the ZFS pool.
Needless to say, I'm now copying the data to ZFS, and before tomorrow, these two disks will be a new ZFS pool.

Cloudflare's problems today confirmed what I have known for a long time: if a customer is down for half an hour due to some kind of server issue (disk replacement, etc.), they immediately start saying a way must be found to avoid it.
When it's Cloudflare that goes down for hours, they accept it with resignation.

Major Cloud providers have all suffered significant outages recently. At an unprecedented rate.
They are firing engineers because of their 'AI'.
I wonder if these things are related.

Where Have You Been for the Last 20 Years?
Walking away from the BSDCan final reception at Lowertown Brewery, Ottawa. The perfect end to a life-changing experience.
"Just" 270 MB for...an idle server?
Debian is still a great distribution but let's measure the ram consumption of a freshly installed *BSD or Illumos based server. The numbers are totally different.

The Lady of the Clock
The search for an antique clock turns into an encounter with its elderly owner and a promise to become the custodian of a century of memories. A personal reflection on legacy, loss, and the stories objects carry.
