Hello,
500 Mb is indeed quite large (even with 2 Gb of RAM). One possibility
(once you have picked the peaks for a spectrum) is to go to stored contour
files (a couple of bugs in the graphical interface for that having been
fixed in the last day or two). The idea behind these is that instead of
having to load all the raw data into memory, you only have to load the
contours. The downside is that you cannot change the contour level
(except by calculating the contour store all over again). The problem
with having lots of data is that not all of it can be stored in memory at
once, and that is when you will get hammered. (Especially if the data is
not on your local disk, but over a not-very-good network.) To create
stored contour files go to Experiment --> Edit Spectra and click the
Contour Files button and then click Create New File.
On another side of this issue, the Tk is definitely having the graphics
getting refreshed too often, and this is definitely not helping. This is
something we are intending to look at when there is time.
