performance

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++...

Hello, I am having bad performance in my laptop's FreeBSD installation, after installing `drm-kmod`, xorg works but it's lagged, like it has high CPU usage (the CPU usage is normal) and the RAM usage is also normal. Here's my Xorg.0.log http://ss.suragu.net/f/ymoi7/xorglog.txt and my the only...

Here's a benchmark I did today that compares desktop and WM graphics performance in Motionmark 1.2: Mate desktop: https://i.ibb.co/ggZDN02/Screenshot-at-2023-02-19-14-37-09.png PeKWM window manager: https://i.ibb.co/pjLPHj8/2023-02-19-142216-1920x1080-scrot.png dwm window manager...

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...

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): https://www.phoronix.com/review/chrome-80-benchmarks/4 Phoronix results with the 5950X (new 16 core CPU)...

In the past I always had a maximum result of +- 63.1 on Speedometer 2.0 Today I updated my system, and although it was a minor version change, I have much higher performance in the main browser benchmark: https://i.ibb.co/wSr7WXF/Screenshot-2022-07-28-15-38-40.png Chromium should now perform...

I'm running bhyve vms that show very bad I/O performance and I'm wondering what factors may be causing this? A couple details: I'm testing with a simple dd if=/dev/random of=test bs=1M status=progress and yes, that's not very scientific. Since I'm seeing many factors worse I/O perf than...

Hi FreeBSD Gurus! We have FreeBSD (12 but planning to update to 13) installed on a old (born in 2014) server: PCIe 3.0 motherboard Intel C600 Series with 2xXeon 8-Core CPU with a 6 of PCIe v.3 4 of x8 slots (dedicated to CPU 1) 2 of x16 slots (dedicated to CPU 2) Both CPU are: Xeon E5-2670...

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...

Greetings. Having mariadb105-server-10.5.13 running on FreeBSD 13 with ZFS. (A physical, dedicated server: CPU: AMD Ryzen 5 3600 6-Core 3593.32-MHz CPU and 64 GB RAM) My WordPress website sometimes getting random-visitors attacks/DDoS (hundreds of http GET requests instantly towards randomly...

Hi people, 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 Original Intel EXPI9404PTG2L20 EXPI9404PT PRO/1000 PT Quad Port Server Adapter Intel 82571GB Launch Date Q1'07 PCIe 1.0a Specification...

I notice that whenever I run make buildworld, it is using only a single CPU. Is it possible to make it use all the CPUs?

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...

Hi 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 - reboot - freebsd-update install - delete all ports installed - portsnap fetch update - install...

POST HEAVILY EDITED: actually the limitation is not about FreeBSD 12.2 Hello, 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...
