DELAY MODE
       If  the delay mode is enabled, req/sec throughput is maximized at the expense of latency. This mode actually disables TCP_NODELAY option of
       all sockets.  The practice of this feature is as following:

       - run some scripts that watches load of the kumo-server. (see source code of kumotop)

       - if the load of kumo-server becomes high, enable delay mode by kumostat set_delay command.

       - if the load of kumo-server becomes low, disable delay mode by kumostat unset_delay command.

EXAMPLE
       $ kumostat svr1 items

       $ kumotop -m mgr1 hscheck
