[Solved] Calc scrolling change from Air to Pro
Posted: Wed Aug 23, 2017 11:23 pm
Hi,
I used to work on a MacBook Air 2011 and Calc scrolling was really really smooth. I open large files with sometimes over 200,000 rows and I scroll very quickly with the touch pad. Most rows contain random phone numbers and my goal is to notice patterns. This is quite easy when scrolling is smooth.
Two days ago I got a 2016 MacBook Pro 15''. I migrated the Air to the Pro with the OS option. Now scrolling is choppy, really choppy. This used to happen on the Air only during super high stress on the machine, like streaming + having a ton of files open and so on. Otherwise super smooth.
Settings are identical, I updated to 4.1.3 from 4.1.3, it did not fix it. I notice that when scrolling the CPU usage gets very high on the Pro. This is so weird. The 2011 Air is super underpowered compared to the 2016 Pro. The Pro handles everything the Air struggled with at barely 1% CPU usage. The moment I start scrolling it goes very high and the laptop even gets a bit hot. Any ideas what is causing this?
EDIT:
CPU usage when OpenOffice is open with the huge cvs file- 0-0.1% by Open Office.
CPU usage with PopCorn Time streaming 1080p movie to chromecast + Chrome open with a lot of tabs + a lot of other small programs- 3% max.
CPU usage when scrolling in OpenOffice in the 0.1% file- 74%
There is something seriously wrong there. The behaviour on the Pro is identical to the behaviour on the Air when the CPU was really stressed. Calc scrolling shouldn't stress a quad-core i7 that way
