Flush Cache when?

Help says:

 

Purpose 

Performs an immediate flush of the FileMaker Pro internal disk cache to the computer's hard disk.

Description 

This operation is normally done periodically during idle time and after extensive structural changes, such as converting files and defining fields.

Examples 

Perform Find [ ]
Sort Records [Restore]
Go to Record/Request/Page [First]
Replace Field Contents [script examples::Serial Number; Serial numbers]
Flush Cache to Disk

 

 

So does this flush only the table I'm on, all tables in the file, both files if separation, all files being served at the time?  

 

I see it used to force refresh if a portal won't refresh.  I also see it used when in testing it isn't necessary.  I read that it should not be used because it slows a system down.  Slows it in what way - because the index must be created again for the table?

 

I am thinking of using a process with a Preference single-record table but it will need to flush cache after every change.  Do you think that would be bad on my file?  Would other people in other tables get flashed also?  Why would they flush cache after a Replace Field Contents when I show it wouldn't be needed?  Why would you flush it during idle times anyway?  I guess the flush after structural change makes sense if Users are viewing records and the result would change.  Is that why it says to do it then?

 

I'm beginning to get this stuff but it seems that I have major holes in my understanding and I have been unable to plug them.  This website has been the greatest find since my wife.

Any input at all on this?  I have researched and it is not really covered anywhere.  I appreciate any ideas.

You won't find any official word from FileMaker on this site. If you want to converse directly with FileMaker tech, go to community.filemaker.com

My comment on the original question is: flushing the cache doesn't hurt anything, it doesn't affect other users, and there's generally no need to worry about it unless you're having a specific issue such as refreshing a portal or something like that.
