only 800MHz? AMD Opteron 1381 of dacentec.com

in General

I have bought one server of dacentec.

cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 16
model : 4
model name : Quad-Core AMD Opteron(tm) Processor 1381
stepping : 2
cpu MHz : 800.000

    Possible in 'power saver' mode. It's normal.

  • duduyxduduyx Member

    Maybe it's KVM machine , Not Dedicated server

    Absolutely not. Try execute benchmark to know 'real speed'.

    What's wrong with having power scaling enabled? If everyone disables it then they will use more power and everyone will foot the bill.

    I try run super_pi on my server,and print /proc/cpuinfo , and get cpu MHz :2500.000

    apt-get install cpufrequtils

    then nano /etc/default/cpufrequtils

    and put: GOVERNOR="performance"

    save and reboot and then it will be running at 2.5GHz all the time.

    OR you could just leave it, it's in ondemand mode right now so it will be at 800MHz until you hit a certain load and then it will ramp up.

    The time it takes a CPU to change it's frequency is on the order of milliseconds, much too high for latency-adverse applications.

    However, for most web servers, it doesn't mean much.

    Every Dacentec thread I see just makes me wanna buy a dedi from them lol. Iuno how to explain it

    The likely hood of these using it for high use programs? Low

    And it's not even really high-use programs that suffer. It's programs that are adverse to latency, like gaming servers and the sorts. Honestly, if it were me, I'd require justification before turning off CPU scaling. Most programs that users run on a VPS from LEB/LET don't give 2 shits about latency.

    Plus, with an ondemand scaling algorithm, computers are relatively smart about what performance they need.
