Bought 2 VPS's, same node & package, different cpu speed?
Hi.
I bought 2 VPS's around a year ago and today I reinstalled the OS and started the installation of CentMinMod on both of them at the same time.
I noticed one finished installation minutes before the other one finished.
So then I asked myself why, and took a look at
cat /proc/cpuinfo
And was surprised when I saw one had a much higher cpu MHZ than the other.
What's strange is I bought 2 VPS's, same package, and their on the exact same node according to SolusVM.
Anyone know why the CPU mhz varies? Did I just get lucky (aka glitch), or is the number randomized between a certain range every time a VPS is deployed?

Contact their support to set the correct CPU speed
Is there a way to know what the correct CPU speed is supposed to be? Because if it's supposed to be 755 Mhz then their going to reduce the 2799 Mhz one. Which would work against me.
On the other hand, if it is supposed to be 2799 Mhz then that would work out great for me
755Mhz is pretty unusual,
If it's 755Mhz which they offer then change the host.
Go ahead & have a ticket
I don't know, you should ask their support what is the correct CPU speed first if this information is not in your VPS plan description.
This is probably Intel CPU frequency scaling. The CPU runs at lower clock speed when idle, runs again at high speed when there is CPU load. Run something CPU intensive in the background, then try to cat /proc/cpuinfo - you will see the high frequency.
I.e. everything is OK.
Okay I will submit a ticket as soon as Crissic's website is back online.
Currently http://my.crissic.net/ shows
403 Forbidden
nginx
More info about what speedstep is here - http://en.wikipedia.org/wiki/SpeedStep
Crissic website connects just fine. It could be hardware issue, motherboard/processor clock frequency error
looks like their site is back online. I have submitted a ticket.
Please update after they reply, I'd like to know too!
Could be Intel SpeedStep enabled on one node and not the other.
SpeedStep usually has a low of around 800Mhz
Ok I will.
Also, I just realized their website was never down.
When I type my.crissic.net in my browser it shows me
It does not automatically go to https
/my.crissic.net/
This is what it looked like to me as well
haha, no shortcuts
Just fired up my crissic box and found exactly the same
http://prntscr.com/5u1s4o -- SpeedStep enabled.
nope, just checked with an idle vps, frequency shows as per processor specs
Their both on the same node, and I just tried running some intensive stuff and the CPU remained the same @ 755 Mhz
What CPU intensive did you run? Try dd if=/dev/zero | md5sum
And at the same time in a different ssh terminal in the same VPS do cat /proc/cpuinfo
Done, and still the same CPU
Oh and I was using UnixBench.
BTW the results of your command were
d if=/dev/zero | md5sum
^C66093505+0 records in
66093504+0 records out
33839874048 bytes (34 GB) copied, 182.317 s, 186 MB/s
correct me if I'm wrong but cat /proc/cpuinfo just reads processor's information and does not gauge in any way
What command do you recommend?
AFAIK lscpu does not work on any crissic VPS's.
I tried it on their Centos 7 and Centos 6 templates.
lscpu
lscpu: failed to determine number of CPUs: /sys/devices/system/cpu/possible: No such file or directory
When I asked support about it they just marked my ticket as Answered and never replied, & Centos 7 was a pain to get used along with the firewalld issue as mentioned in my other thread, so I use 6 now.
Sure they are on same node?
Both on Jax06
Both running CentminMod
lscpu not working is just an OpenVZ thing I think
Have your provider run this on the node, then reboot your VPS. Problem solved.
@shovenose would be a useless waste of electricity though.
Eh, it doesn't make that much of a difference and will offer a faster, more consistent experience for customers services. And you won't get a bunch of tickets of people complaining about slow MHz numbers - that alone is worth it.
Something like cpuspeed is great on a laptop, desktop, whatever, but was not designed for a multi-user environment like a server.
I've full frequency there
# cat /proc/cpuinfo
processor : 0
model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
cpu MHz : 2659.951
processor : 1
model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
cpu MHz : 2659.951
processor : 2
model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
cpu MHz : 2659.951
processor : 3
model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
cpu MHz : 2659.951
The only reason I'm complaining is because one VPS out performs the other.
Took much longer for the one with the "smaller" number to install CentMinMod than the other
If anyones wondering about the ticket, still no response. It's a Sunday so a response should be in by tomorrow.
It's a dual cpu server (dual X5650), highly possible 1 vps is on processor A and the other on processor B
