The 7z LZMA benchmark runs dummy compression and decompression tasks to measure the overall performance of the system. It reports measurements in MIPS (million instructions per second) which give an idea of the computer’s raw processing power counting all factors. 7z LZMA compression is a multi-threaded work-load. This means that it can utilise multiple cores… Read More »
Sysbench is a command-line tool that is designed to test and benchmark database performance, but with certain options it can also be used to run tests to measure the raw performance of cpu, ram and storage devices as well. These tests can give a brief and fairly accurate assessment of the system’s performance. In this… Read More »
Getting detailed information about the wifi adapter on a linux system is not straight forward using gui tools. However there are simple commands that can do the trick. In this article we shall take a look at commands like iwconfig, iwlist, iw and nmcli which can be used to probe details about the wifi adapter… Read More »
CPU temperature Ever noticed your cpu fan making a lot more noise than usual ? It does so when the temperature of the processor gets high due to high processing. Sometimes, the processor may heat up so much that the system would start lowering the processor clock speed and would show up such a message:… Read More »

Hp Deskjet 1112 In a previous post we talked about the you can buy. In this post however we shall learn about installing the device driver for the HP Deskjet 1112 printer. The HP Deskjet 1112 is a simple color printer. It has no scanner or copier function but can print pretty well and is… Read More »
GPU temperature Nvidia graphics card has its own processor that gets heated just like the main cpu processor. They usually have a heat sink and the high power gpus also have a fan. Its a good idea to monitor the gpu temperature on your system from time to time to ensure that the unit is… Read More »
The dd command on Linux can be used to measure the read and write speed of usb/pen drives and solid state drives (ssd), and this tutorial shows you how.
Check details about the processor/cpu like the architecture, number of cores, hyperthreading support etc on Linux using lscpu and hwloc commands
Here is a quick list of 10 commands that you can use to check the partitions on hard drives and disks on your Linux system and how much space each partition has.
