The question really doesn't make much sense without more context.

Find however much memory you have available when you are running your  
application and use that (be sure to count however much memory you  
need for the kernel page cache when you calculate "available memory").

You could start with very little (say 128MB) and then monitor how  
much you are using it.  For some applications it might be fine, for  
others it'll be completely unusable.
