Get this on a regular basis, separate error message for each of the 4 cores:

"Log Name: System
Source: Microsoft-Windows-Kernel-Processor-Power
Date: 17/07/2015 22:30:19
Event ID: 37
Task Category: (7)
Level: Warning
Keywords:
User: SYSTEM
Computer: Laptop
Description:
The speed of processor 1 in group 0 is being limited by system firmware. The
processor has been in this reduced performance state for 71 seconds since
the last report."

This is a fairly new Acer laptop with Intel I5 4 core CPU, 4GB RAM and 1TB
HDD and since buying it has seemed to me a bit sluggish. I am fairly
meticulous about regular cleanup, defrag, malware & AV scans, startup
programs etc. OS, BIOS & drivers up to date.
Clicking the more info link in Event Viewer tells me no info on that error.
Is this the cause of the sluggishness and what if anything can I do about
it?
Any advice appreciated.
