Hi Herb,


Is the application responding very slowly, or is the application responding very slowly with a specific document?


How big is the document you are using?

How many sheets (tabs); how many tables; how many rows and columns in the biggest table?

What formulas are you using? Some functions take more processor time than others.

When did you last quit and restart Numbers?

When did you last restart your Mac?

How much memory does your Mac have?

How much is being used?


All of these can be factors causing Numbers to slow down. More information is needed to provide any more specific answer.


Chances of a virus being the cause are pretty slim.

Barry


PS: You've posted this question in the AppleWorks area, dedicated to discussion of an earlier (and long discontinued) Apple productivity application. I've asked the hosts to transfer it to the Numbers for Mac community.

Thanks for the response.

In answer to your questions...

Is the application responding very slowly, or is the application responding very slowly with a specific document? It's the app, not the document


How big is the document you are using? Small...one sheet

How many sheets (tabs); how many tables; how many rows and columns in the biggest table? Six columns; 30 rows

What formulas are you using? Some functions take more processor time than others. Currently none.

When did you last quit and restart Numbers? Tried several times without better performance

When did you last restart your Mac? At least twice

How much memory does your Mac have? 4GB

How much is being used? ?? don't know where to find this

The app runs OK for the first 4-5 inputs, then slows to a half minute +/- wait before input appears on screen

HI Herb,


"How much is being used? ?? don't know where to find this"


Memory use and activity (which processes are hogging the CPU) can be found using the Activity Monitor.

Activity Monitor is in the Utilities folder in your Applications folder, but the quickest way to get to it is probably by clicking the Spotlight magnifier at the right end of your menu bar and typing Activity..


Nothing in your description that would point to anything causing the slowdown. Possibly something running in the background (which Activity Monitor should show you in the process list.


I could send out a Bat Signal to the community members who know more about the inner workings. They'd likely be able to provide more help than I or others regularly in this community could. Shall I do that?

This is a new version of Activity Monitor to me, as I just recently jumped from Mountain Lion to El Capitan. The display is quite different, and takes some getting used to.


Memory pressure likely refers to the amount of RAM you have available compared to the amount you are currently using. Currently using depends on which applications you have open, whether they're active, or just hanging around and checking regularly to find if there's work to do, and how 'heavy' their current tasks are.


How far the line runs across the bottom is just a measure of how long the application (Activity Monitor) has been running (with this page displayed) It's the height of the line that indicates the demand on memory. If it stays down near the bottom, it won't be lack of system memory that's slowing things.

Barry
