currently testing the AMD workstation with the KINGSTON SKC3000D2048G NVMe, directly attached to one of the 2x NVMe slots (no RAID), as this NVMe drive seems to offer excellent price-to-disk-size-and-performance-value, if it is a kingston-quality drive, then there should be […]
hardware used: AMD Ryzen 5600G Gigabyte Aorus B550 Elite AX v1 (Rev 1.1) 2x NVMe Kingston SA2000M81000G those are DATACENTER capable NVMes! (at a pretty nice price!) energy meassurements: meassured wattage when PC was idle (doing nothing): GNU Linux Debian […]
Even managed to run this system off solar power in spring, summer and autumn, not winter X-D Of course RISC(V/ARM) based (mobile) gaming systems would be those that use the least amount of power per frame 😀 But it seems […]
check this out: When will Intel & AMD release their first ARM based SoC? “Intel is working on a new SoC (system on a chip) that will compete with the ARM-based designs that have dominated the mobile market for several […]
ZFS is probably THE most controversial filesytem in the known universe: “FOSS means that effort is shared across organizations and lowers maintenance costs significantly” (src: comment by JohnFOSS on itsfoss.com) “Mathematicians have a term for this. When you rearrange the […]
because Win 10 compared to Win 7 is incredibly slow, a way to upgrade an older ASUS Mainboard was found RAM was increased from 8 GB to 32 GB it actually had an M.2 slot for the MZ-V8P500BW NVMe SSD […]
raid10 combines the speed of raid0 with the resilience of raid1. watch out: shingled hdd are not good for RAID! setup of GNU Linux mdadm software RAID10 is actually pretty straight forward: no need to do any partitioning. # tested […]
first off the praise: kvm-qemu is a high performance nicely scriptable virtualization system if it works, it can do pretty things 🙂 especially like the x11 forwarded virt-manager gui over ssh (yes it is a bit slow… but simplicity at […]

update: Starlink reduced price to 80EUR! 😀 PLUS: THE HARDWARE IS FOR FREE! (the very good hardware alone is worth ~2000USD!) Thanks Elon! 😀 Support SpaceX: mankind’s only hope to ever reach Mars! order Starlink now! Update: Amazon […]
update 2022: next to the good old (non-destructive if used correctly) “dd” is still the way to go for benchmarking harddisks under GNU Linux. a simpler one is “gnome-disk-utility” also interesting but not very simple in installation & usage (complicated! […]
“first Benchmarks of the KX-6780A. China just developed it’s own x86 CPU with the performance of a Intel Core i7 2600 (4C/8T, 1,401 points) from 2011 the eight-core CPU-Z achieves 171 points in single-core and 1,396 points in Multi-Core comparison […]
apologize! games = windows, still ? (although there are 6000 steam games running on linux) the very first “Open Source GPU” is in the making: https://www.crowdsupply.com/libre-risc-v/m-class “The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the bedrock. […]
got the server cheap from ebay. has unfortunately only 4x 2.5″ SAS (3.5″ would be better = more storage) one SAS drive already faulty. using the native Hardware RAID10 (4x 75GByte Hitachi HGST Ultrastar C10K600 450GB (HUC106045CSS600) 2,5″ SAS2 64MB […]

update: with more or less CPU usage this device uses like 6kWh per day (rough estimate over 30 day measurement) it runs pretty quiet even on 100% CPU load 😊👍🏻🖖🏻🍻 got it cheap on eBay and wanted to take it […]
this is a very very basic sequential harddisk write test performed on host and guest. there are multiple ways, how you could improve the performance: Use fixed size disks Allocate RAM and CPUs wisely Install the Guest Additions enable host […]
htop is really a cool tool that also lets you show per-process io disk read write usage. (what process is writing / reading how much bytes right now) start htop and hit F2 to get into setup screen. from columns […]
want to buy one? check on ebay for “sun” and “sparc” recipe: what you will need: a T1000 alternatively: ear sealing headphones + music. a LAN switch with DHCP-server/router attached LAN cables (atleast 4x (1x DHCP-server, 1x workstation/client, 1x server […]

if you want to find out what chipset / mainboard your PC / Laptop / Notebook is using and other details about the hardware. unfortunately this is not a straight forward task… and works better / worse depending on the […]
update: while this benchmark is still valid, very simple, very cross platform, with a focus on the team cpu (why is there no multi core md5? (putting many many core arm servers at disadvantage) + harddisk (two very important components) […]

smart first: one might want to check the SMART status of one’s harddisks to make sure, they are running under normal conditions and do not show signs of failure. pre-benchmark preparations: halt as much programs as possible: one SHOULD suspend […]
