Memory usage when creating many tables or large tables

I have noticed that when I work with large tables (30+million lines) that jmp (14.3 64-bit) never seems to use more than 30ishGB.  Or if I have several smaller tables open at once...subsets of a larger table. I have 64GB on my machine but JMP doesnt seem to ever go over 32.

Re: Memory usage when creating many tables or large tables

You don't mention what operating system you are running on.  JMP 64-bit doesn't have limits other than 8TB on Windows (and I think 128 GB on Mac) that are dictated by the OS.  Some older Windows Server OS's have 32GB per process limits.  

 

If you are on Windows, you might check the swap file size to make sure it is adequate for your amount of RAM.

It is Win10 64-bit 1709. Page File is recommended at 17121 MB Suggestions on what it should be.

That should be adequate, so it's probably not the issue.  If you have a lot of drive space you could try upping it to 65000 just to see if there is any difference.
