c++ - RAM-disk vs Boost interprocess communication -


to let set of processes communicate, advantages , disadvantages between:

  1. ram-disk
  2. boost interprocess communication

a ram-disk allows communicate programs use files.

how big performance penalty of ram-disk due file system interface replicated?

it's false dichotomy.

if you're sharing via

  • files on ram-disk - you're still using memory-mapped files (implemented boost interprocess)
  • named pipes (fifo's on unix) you're still using ipc (because pipes or socketpairs ipc primitives).

you can't /avoid/ ipc using ram disk.

in fact, sends alarm signals because sounds you're assuming somehow "simpler" using ram disk. in practice, it's simpler if don't proper locking. source of bugs, though.
