on one of my storage servers (12 spin disks), I run geli with AES CBC encryption due to prevent physical data hijacking by evil data center personel ;).
As far as I know AES CBC is slower than AES XTC. How ever, I would like to ask you about your performance experience regarding...
What is real difference in network performance (in real life complicated environment, i.e. a lot of packets different sizes, etc...) between this one

Hi, hardware gurus!
How exactly BSD pf performance (in matter of low latency, high PPS, etc) depend on bus frequency, main CPU frequency and L2/L3 cache size in multi-package (mean physical multi-CPU, like Intel E5500/5600, E5-2000 series) server systems that intend working as border firewall...
I notice that after successful installation of KDE on FreeBSD, there are many files linked into the kernal, as shown by the command "kldstat".
(1) I wondering where is this configured - what file(s)? I checked /boot/loader.conf and /etc/rc.conf and couldn't find them there.
(2) Is there a...
Did someone notice performance degradation of the Bhyve VMs after upgrading to the 12.2?
I followed typical flow to upgrade:
- freebsd-update upgrade -r 12.2-RELEASE
- freebsd-update install
- freebsd-update install
- delete all ports installed
- portsnap fetch update
POST HEAVILY EDITED: actually the limitation is not about FreeBSD 12.2
in our lab we have a few HP Proliant DL360g8 with 32 GB RAM that we use to run jails.
Each server runs ~6000 simple jails that have only sshd and syslogd as running services.
They currently run FreeBSD 9.2, but I'm...
Hi everybody! Happy & healthy 2021 !
My newly assembled FreeBSD server is now up and running. 🥳
Summary of the setup:
CPU: Intel(R) Pentium(R) CPU G4560 @ 3.50GHz (3504.17-MHz K8-class CPU)
Storage: ZFS RAIDZ2 using 5 Toshiba N300 7.2K 4TB
Memory: 32GB, I limited ARC to 16GB in...
In my home PC, one of my two HDD that I have in (btrfs) RAID 0 failed. So, I am shopping for the replacement. I am planning to install FreeBSD (zfs) and set up RAIDZ (buying 3 SSDs).
Now, I am reading everywhere that mirroring 2 disks (1 vdev per disk) is faster than RAIDz1 with 3 disks. And it...
I'm currently running FreeBSD 12.0-RELEASE-p12 with XFCE and it is slow: top reports Xorg using 90+% of CPU resources on idle state.

Can someone help me troubleshoot? It is a DELL Latitude E7470 on which I...
We have a FreeBSd-12.0p3 host that originally started life as version 10.2. It is used to host a number of BHyve vms, all but one of which are running FreeBSD-12.0. as well. INET09 is supposed to be a CentOS-6.9 system but will not boot into the installer. SAMBA-01 is a FreeBSD-10.2 system...
I'm currently planning to deploy a set of FreeBSD machines that provide storage over NFS to virtualization hosts (Proxmox). I already have several Proxmox nodes running but currently all VM disks are in the node's local storage. While migration does work it does require me to shut-down a VM...
Hi, I'm running FreeBSD 11.1 on an Fujitsu Siemens RX300 S6, with two Xeon L5640. I've to use for software legacy reaons an Ubuntu 16.04 LTS to develop a large set of PhaseOne IIQ images (SDK is released for Linux 16.04). I use bhyve and it worked very well out of the box . Thank you FreeBSD...
I recently upgraded from 10.3 to 11.1 and ever since my Xfce desktop has been behaving like a drunk laggard. Things like multiple chrome windows with a few tabs on each (say 5 to 7) causes the desktop to slow down considerably.
Some websites do not even open now taking forever until I...
I am migrating from Debian GNU/Linux to FreeBSD. I could be using KfreeBSD, but I prefer blending-edge and also become part of a community, so I will not stick to Debian, although I appreciate the spirit.
The server board has 32 CPUs, 32GB of RAM, 1 x SSD and 5 x SATA disc...
I use FreeBSD 11.0 with an Ryzen R7 1700X Processor since March, the first thing i recognised switching over to Ryzen was significantly improved performance compared to my Phenom X6 1100T. The Power-Consumption has become very low.
I struggled a lot of Problems within wine, having very low...
Hi. I'm building a new system for a small data warehouse and have been testing disk performance in various zpool configurations using up to 14 drives. Every configuration seems to be performing as expected except for sequential reads across mirror sets.
Could somebody please either correct my...
I want to ask, what do you think about such problem. Or maybe this is not a problem at all?
All we hear about Moore's law and it seems to work for current days. So from 90's to 2017 CPU performance, RAM capacity and HDD capacity grows in nearly 1000 times.
But why all today's desktop...
