ebd96ada3c Misc. experimental features. (1) thread affinity (2) event_base_flag_precise_timer (3) configurable agent port (4) per-connection qps moderation 2013-04-15 13:27:06 -07:00

7ca3e57c6d Add --skip option: By default, mutilate tries to maintain a long-term QPS average by issuing requests as quickly as possible until it catches up with where it 'ought' to be. If you give the --skip option, it will instead just skip sending requests that are already late. 2013-03-12 15:27:29 -07:00

fc0f1a78a4 1. Implemented --measure_* options to reasonably separate
configuration of measurement client (mutilate master) from
load generating clients (mutilate agents).  Use -C and
--measure_depth to approximate open-loop measurement control
(i.e. so long latency requests don't screw up the sample
population), and use -Q to ensure that you see minimal
client-side queuing delay.

2. Quickly documented agent "protocol".  Lots of improvement
to be had here...

960b30dc7b Add -M (measure-mode), where master client only opens 1 connection per thread (to avoid client-side queuing delay). 2013-03-06 21:55:24 -08:00

4e8d2f6d10 Merged Stephen Yang's and David Terei's binary protocol and SASL implementations.
I ended up cherry-picking different parts from each implementation.
I liked David's changes to the read state machine to implement SASL.
I used Stephene's implementation of the binary protocol integrated with
the ASCII protocol.

46015b29ac Added location parameter to GPareto distribution. Validated value-size distribution against Atikoglu's paper by comparing CDF and PDF. 2012-08-24 14:02:57 -07:00

386320d266 Initial check-in.
This is extracted from another git repo.  This is the first release, and
the prior commit history is not terribly interesting, so I'm not going
to bother using filter-branch to try to cleanly isolate the history for
this tool.

Cheers.
