[[email protected] ~]$ lscpu You need to use the /proc/cpuinfo file. :-) For Linux-specific methods, you can access /proc/meminfo (and /proc/cpuinfo, if you can't be bothered to parse cpuid responses). I'm reposting here and have attempted to weave in some of the great comments we received from the Community. The “/proc/cpuinfo” file is a virtual text file that contains information about CPUs (central processing units) on a computer. System load/CPU Load – is a measurement of CPU over or under-utilization in a Linux system; the number of processes which are being executed by the CPU or in waiting state. processor : 4 And working properly. Even though the server responded OK, it is possible the submission was not processed. clflush : Cache Line Flush instruction 1. How to identify the Processor (CPU) The cpuinfo method is available on every Debian computer. To determine the type of processor you are using, run the following command: One way to find out how many physical socketed CPUs there are is to eliminate any extra cores: [email protected] ~ $ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte … It’s kind of like a mother bird with more open beaks pointed at her than she has the grub for. @Hristiyan – You might be using an application such as cpufreq. There is no good reason to use prefork at all on any processor, except if you are running Apache modules which aren’t thread-safe. That is correct – however the clumsy command should be run as one very long command all at once and you should only get 1 output result. Load average – is the average system load calculated over a given period of time of 1, 5 and 15 minutes. Cache information not available But I don’t see any issues with end user, whereas my top proc is mysql demon for DB, pls see below.

Get Processor Type. Thank you, Tricky, for the answer. Identifying the type of processor using the proc/cpuinfo file does not require installing any additional programs. Using "lscpu" command. As to what is too high, that doesn’t just depend on the number of processor cores but also on what exactly you’re doing. Below are the steps to determine the processor type for Windows, Mac, and Linux. $ grep processor /proc/cpuinfo. sse : SSE instructions Please check documentation before using. The SysInfo of XFreq is using this instruction to show all features of the processor. Neofetch and Screenfetch. ss : Self Snoop Two common entries are processor which gives CPU number and bogomips; a system constant that is calculated during kernel initialization. cpuid level : 1 However if you have a single VPS on a quad-core physical server (there are some scenarios where this is a good idea) then it makes sense to have all 4 cores assigned to the single VPS. The cpu_set_tdata type is implemented as a bitset. Other commands to check CPU information in Linux. You can simply view the information of your system CPU by viewing the contents of the /proc/cpuinfo file with the help of cat commandas follows: To get a little specific, you can employ grep command– a CLI tool for searching plain-text data for lines matching a regular expression. vme : Virtual 86 Mode Extension From new users to hard-core users, you’ll find a “flavor” of Linux to match your needs.

The cpu information includes details about the processor, like the architecture, vendor name, model, number of cores, speed of each core etc. Open up a terminal window and type in the following command: sudo dmidecode --type memory. Example – Find out if running Linux kernel (OS) is 32 or 64 bit. The “Architecture” entry tells you what type of CPU you have (where “x86_32” signifies 32-bit and “x86_64” signifies 64-bit). cpu MHz : 2798.083 Linux - Networking: 0: 02-25-2008 02:20 AM: CPU architecture of kernel on install DVDs/CDs: TurboI: SUSE / openSUSE: 5: 09-20-2007 06:52 AM: confusion about architecture type. Execute grep -o -w 'lm' /proc/cpuinfo command to determine if you are using 32 or 64 bit CPU. cpuid level : 5 The explanation on load avg is quite perfect, but I have read somewhere if the load avg is 2 and it has 2 processor then its fine. The small backlog (thus causing the delay) isn’t good but it is not a mission-critical problem and the end-users are still happy. The target also comprises the "system design" of the entire system, be it a supercomputer, a desktop computer or some SoC, e.g. We'd expect cpu bound process to have a If you have a quad-core physical server shared by 16 VPSs it makes no sense to have more than one virtual core assigned to each VPS. Hi there , under Ubuntu Maverick 10.10 i used this line to get CPU Speed Info : dmesg | grep “MHz processor” | cut -d ” ” -f07 | sed ‘s/[.].*//’. Clears set, so that it contains no CPUs. See http://www.redhat.com/archives/nahant-list/2006-January/msg00176.html. Few useful DMI types 0 for BIOS version, BIOS vendor etc. This will give you insight into the performance of the system as well as show how the hardware resources are being divided up across the various running services. Core(s) per socket: 2 They both will make full use of all your processors. Add CPU cpu to set. This is what I got. The "lscpu" command is used to display the information about your CPU in human-readable format. Essential CPU information in Linux. Thanks cyberciti. Get Processor Type. If there are four people serving but usually only around one person waiting it’s ideal. To test whether your Linux computer has a 32-bit or 64-bit CPU and to see what version of Linux is installed, open your terminal, type the following command at the prompt, and then hit Enter: lscpu. The procedure is as follows: Open the terminal application or log in using ssh command. de : Debug Extensions – I/O breakpoints The lscpu command is CPU architecture information helper and can be found under Fedora Linux / RHEL / CentOS v6+ / Debian Linux v6+ and many other latest distro includes this command. Unfortunately if multiple physical CPUs only have 1 core each this returns zero. Type the following command: $ top Sample outputs: Gnome users can install and use the hardinfo method.
