claus, i don't know what stuff your machine is loading on startuup,  
but 700MB initial usage seem to be 'ridiculously' high! maybe you can  
optimise some stuff? i have 1,25 GB and after startup i have 160mb  
being used............

do u really need SO many datapoints in the graphics file? i mean you  
are using a vector format, so you should use tthe advantages of this  
foormat, instead of trying to build pixel pictures inside a vector  
format :) curves can be well optimised using common vector graphic  
tools. also you should make use of the package 'eps2pdf'...

vetortools you might want to try for optimising your graphcics file:  
scribus, cenon, inkscape - all of them freeware...

os x itself needs the 512mb to ruun flawlessly - without advanced  
appplications that is. if i only look at the ram consumption of  
safari (that's why i use firefox!) or itunes/iphoto... hallojulia! :)

yes, the ram does :) the editoor doesn't, because the TeX subsystem  
iss doing the work, not the editor...

most certainly! in ilustratoor is is called "simplify", in other  
programs you can find equally well working functions.... i guuess you  
will cut down the size to 1/50th :)
