Hopefully someone else thinks to Google for this problem and find themselves helped by a similar approach. After disabling Speed Step, I have been running for the entire day at speeds very similar to my desktop. Whatever the logic is that determines when to power down was clearly NOT working as intended on my laptop. I guess that the idea of Speed Step is that the i7 powers itself down when it decides you’d like your system to perform like a 486. On my Dell, this was under the “Performance” settings. Except for every once in awhile, when it would take 6 or 7 seconds.īefore splurging for a new laptop, I decided to take a peek through my BIOS settings and managed to stumble across the culprit: the Intel “Speed Step” feature. But to be thorough, I did remove practically any and every resident program that was running on what should have been a zippy Dell Latitude E6520 with a i7-2720QM (2.20GHz, 6M cache) processor.Īnd yet, running a utility that averaged about 5 seconds on my desktop consistently took 30 seconds on my laptop. In my case, I had been running Ubuntu so most of those tips are moot. Most of the Google results I found when digging around on this subject pointed to usual boring causes of slowness: too many programs being run on startup (which you can test with ms-config if you’re running Windows), anti-virus software, and other boring stuff of that sort.
