   FreeBSD src repository
 
   Modified files:
     usr.sbin/syslogd     syslogd.c 
   Log:
   Where syslogd would have fsync()ed a file in the past, instead set a flag
   FFLAG_NEEDSYNC and fsync the file when select() next returns zero.  This
   dramatically speeds up the process of logging large amounts of data, while
   leaving the essential semantics (that data can be expected to be on disk
   if we crash) unchanged.
   
   In my tests, this speeds up the rc phase of booting by 18-20%. [1]
