Mutilate is a memcached load generator designed for high request
|
|
|
|
|
rates, good tail-latency measurements, and realistic request stream
|
|
|
|
|
generation.

Usage
|
|
|
|
|
=====
|
|
|
|
|
|
|
|
|
|
Type './mutilate -h' for a full list of command-line options. At
|
|
|
|
|
minimum, a server must be specified.
|
|
|
|
|
|
|
|
|
|
$ ./mutilate -s localhost
|
|
|

|
|
|
|
|
|
|
|
|
Mutilate reports the latency (average, minimum, and various
|
|
|
|
|
percentiles) for get and set commands, as well as achieved QPS and
|
|
|
|
|
network goodput.
|
|
|
|
|
|
|
|
|
|
To achieve high request rate, you must configure mutilate to use
|
|
|
|
|
multiple threads, multiple connections, connection pipelining, or
|
|
|
|
|
remote agents.
