How can I make Flex uses less RAM. I have closed other
projects in the Flex Navigator panel but, it is still using a lot
of RAM. It can get up to 600MB. The project I am working on is an
AIR application. It is not a big one, but when I open the .css skin
file, it starts using a lot of RAM.
Closing projects is probably the easiest and most obvious way
to save memory. Make sure you're actually closing, via menu option
"Close Project", and not just closing the folder.
You can also change some default memory settings used in
Eclipse. I suggest Googling "flex builder memory" and "eclipse 3.3
memory" (3.3 is the Eclipse version used in Flex Builder 3 --
search on whatever version of Eclipse you're using) . You'll find
several discussions with tips on saving memory.
