[OS X TeX] Large Figure in Document? (and slow response of TeXShop)

[Claus Gerhardt]

After doing a restart I have to correct myself: 445MB real memory are  
in use, of which 22MB are due to the Activity Monitor, roughly 30MB  
due to Sophos and 17MB due to PGPengine., i.e., about 380MB are  
system related; VM size is 7.7GB and it will typically increase to  
12GB after some weeks. Total RAM is 4.5GB.

Most users will usually have several applications open like Mail,  
Preview, Safari, TeXShop, BibDesk, Console, Activity Monitor. After  
doing this 680MB of real memory is used without having performed any  
tasks with the opened applications. This will change after a few days  
or a week, then typically 2.5GB will be in use.
