Otherwise, if you have a large enough swap, pages of a file on a tmpfs that are not used enough will be swapped. And pages of a file on a regular filesystem that are used enough will be kept in the buffer cache. OTOH, for a wide range of applications that do a lot of small writes, using tmpfs is a huge gain. -- .''`. Josselin Mouette : :' : `. `' `-
