Neil,
I will read the article since I am not fond of Vista's memory allocation method and wish to learn more how to work with it. Indeed, I am limited to run my analysis on weekly data since using daily data requires a too big memory allocation to Stata under Vista's 32-bit system. (I guess I will migrate sooner rather than later to a Linux 64-bit system, hoping for a smoother, more versatile, operating system.)

However, given the current issue at hand, I have now tested Martin's tip to set the memory to 100M after the session has finished. It then gives back the claimed RAM and I am again down to an approximately 32 percent RAM usage.

This is much appreciated since I now again have a snappy Stata without having to restart it after each bout.

/Joachim


Quoting Neil Shephard <nshephard@gmail.com>:

BTW - a simple example of how this would be useful is if I was using
The GIMP (http://www.gimp.org/) under Linux and then closed it down
when I'd finished, its still actually sitting in RAM, and if I start
it up again it will come back from RAM instead of having to be loaded
into memory again.

Apologies for the poor grammar in the previous message.

Neil
