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.
Examples
$ kumostat svr1 items
$ kumotop -m mgr1 hscheck
