Hyper-threading&Core number influence on Windows booting time

post #1 of 3
Thread Starter 
Hello!

I am very much interested in effect of number of cores and Hyper-Threading function on time that Windows 8 / Windows 7/ Window XP boots up. I cannot check it myself (old e8500), so I ask You for help, if You are interested in topics. Idea is to measure time of computer booting up at different number of cores and Hyper-Threading off/on with these three different systems. So it goes like that:

Cores: 1 Hyper-Threading:OFF
Cores: 1 Hyper-Threading:ON
Cores: 2 Hyper-Threading:OFF
Cores: 2 Hyper-Threading:ON
Cores: X Hyper-Threading:ON&OFF


I am just interested in how well core number scales with Windows 8 boot optimization. Also, I wanted to find out if any core shared resources will be a bottleneck on Hyper-Threading function. Please post Your results, operating system and processor.

I don't think you can select HT on/off per core. Its either all or nothing. Secondly, an i3 paired with a SSD would boot wayyyy faster than any i7 paired with a mechanical drive.

Sure, I didn't really answer your question, just stating that boot times these days aren't really CPU limited but based on the hard drive

I realise thah. But system will be same for cpu so we have solved issue of hdd\ssd\sshd difference. We will be comparising only difference in current build. If the system will start to slow down with less cores, it means it is due to lack of multithreading. Also, I think it is possible on some boards to turn off cores. So You basically turn off 2 of 4 and leave Hyper-Threading on and here You have. But it will be nice to have someone to confirm it. You dont turn off hp for single cores, You turn off cores.
