tool: D4: kmemcache 0.4


tool: D51: -p <num>      TCP port number to listen on (default: 11211)
-U <num>      UDP port number to listen on (default: 11211, 0 is off)
-s <file>     UNIX socket path to listen on (disables network support)
              XXX: must be absolute path
-A            enable ascii "shutdown" command
-a <mask>     access mask for UNIX socket, in octal (default: 0700)
-l <addr>     interface to listen on (default: INADDR_ANY, all addresses)
              <addr> may be specified as host:port. If you don't specify
              a port number, the value you specified with -p or -U is
              used. You may specify multiple addresses separated by comma
              or by using -l multiple times
-r            maximize core file limit
-m <num>      max memory to use for items in megabytes (default: 64 MB)
-M            return error on memory exhausted (rather than removing items)
-c <num>      max simultaneous connections (default: 1024)
-v            verbose (print errors/warnings while in event loop)
-vv           very verbose (also print client commands/reponses)
-vvv          extremely verbose (also print internal state transitions)
-h            print this help and exit
-i            print memcached and libevent license
-f <factor>   chunk size growth factor (default: 1.25)
-n <bytes>    minimum space allocated for key+value+flags (default: 48)


tool: D18: -L            Try to use large memory pages (if available). Increasing
              the memory page size could reduce the number of TLB misses
              and improve the performance. In order to get large pages
              from the OS, memcached will allocate the total item-cache
              in one large chunk.


tool: D5: -D <char>     Use <char> as the delimiter between key prefixes and IDs.
              This is used for per-prefix stats reporting. The default is
              ":" (colon). If this option is specified, stats collection
              is turned on automatically; if not, then it may be turned on
              by sending the "stats detail on" command to the server.


tool: D98: -R            Maximum number of requests per event, limits the number of
              requests process for a given connection to prevent 
              starvation (default: 20)


tool: D23: -C            Disable use of CAS


tool: D20: -b            Set the backlog queue limit (default: 1024)


tool: D43: -B            Binding protocol - one of ascii, binary, or auto (default)


tool: D68: -I            Override the size of each slab page. Adjusts max item size
              (default: 1mb, min: 1k, max: 128m)


tool: D88: -o            Comma separated list of extended or experimental options
              - (EXPERIMENTAL) maxconns_fast: immediately close new
                connections if over maxconns limit
              - hashpower: An integer multiplier for how large the hash
                table should be. Can be grown at runtime if not big enough.
                Set this based on "STAT hash_power_level" before a 
                restart.
