Can anyone point me to where I might find information if and when disk I/O can/will be cached by FreeBSD, e.g.: Is a mkdir cached? Does a mkdir call from an NFS client wait for a positive response from an NFS server prior to handling the next request? And does the NFS server actually commit the update to disk (let's exclude hardware cache for this discussion), prior to responding to the NFS client. Is this configurable? Same questions for symbolic links. -- // Paul A.
