What would be really interesting is to aio_write small chunks to the same 8k page by multiple threads/processes and then wait for the page getting written to disk. Then check how many backends get their wait back at the same write. The docs for POSIX aio_xxx are at: http://www.opengroup.org/onlinepubs/007904975/functions/aio_write.html ---------------- Hannu ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
