Windows – Number of Processors and Computer Speed relation

Does changing the number of processors under Boot Advanced Options affect computer speed?

1

I have Dell XPS 15z Windows 7 Home Premium (64 bit) OS with 4GB RAM, intel i5 processor @2.5 Ghz and 1GB nVidia Graphics.By default, it uses 4 cpu however my system is slow in booting up and seems lazy doing simple things like opening programs and files, i mean the response is slow.

However, when I reduced the number of process to 2 or 3 or 1, the boot up time reduced significantly and system responded quick to any actions but there was lag as it was clear with gaming.

I don't know what to do…..it's so embarassing to have high performance gaming computer but still sucks at doing normal operations especially booting up – it takes more than 4 minutes!

I have very few programs to run at start up.

Any suggestions to improve the speed of my system?

  • The processor is one component of a PC that affects speed, but there are many factors that contribute to a slow computer.

    If you notice speed problems on boot, and opening folders, programs and other files, more than likely it's not your processor that is the culprit, but your hard drive and RAM. Buy an SSD and make sure you have at least 4 GB (preferably 8 if you're gaming) of the fastest memory your board can support. Perform a clean install of your O/S* from a non-OEM disc (crapware is crapware). *Install the **latest drivers for your devices*.

    Disable services that you don't need, as well as any startup programs that can be manually launched when needed.

    To answer your original question, yes, crippling a processor by only using one of its cores will slow down your computer. Would only using one cylinder in your engine make it go slower?
