Possible in 'power saver' mode. It's normal.
Maybe it's KVM machine , Not Dedicated server
Absolutely not. Try execute benchmark to know 'real speed'.
This is on mine, under load.

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.
