I have a command-line executable which I need to run from Java on Windows XP. It uses files as input and output. But I want to avoid the overhead of file IO, so I thought of an in-memory RAM file system.
NetBSD has mount_mfs.
Could you recommend the most convenient way of doing this?
You should also consider whether you really need this (premature optimization, yadda, yadda). On all modern operating systems, filesystem I/O is cached anyway, so frequently-used files are essentially as fast as a RAM disk.
