or the standard deviation would be incorrect.

86ad565956 Updated sync_agent() to be less ridiculous. Still ridiculous, though. 2013-03-13 16:58:36 -07:00

08b2e81c86 Change --skip behavior to only jump ahead if the tx time is at least 5ms (hardcoded for now) behind. Always pacing with timer events was causing it to severely miss QPS targets... 2013-03-13 15:40:00 -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.

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.
