Yes

But why front end memory? After all I can generate the plots from the
kernel directly, but then I get font issues. BTW, I am creating
different plots, my previous code is just an example.

My understanding is that Utilties`MemoryConserve` helps with MathKernel
memory, not the Front End memory.

Yes, that is what I have been doing. It is a pain.

How do you make a loop front end memory efficient besides by using
DisplayFunction->Identity?

The Mathematica Front End crashes when it is using about 1.6 GB or RAM. And I
have 4.5 Gb of RAM. So buying more RAM or closing application will not
help much.

Thank you Chris, Bill and David for your help.
