[Gimp-docs] Jenkins: performance monitoring job for help docs

[scl <scl gplus gmail com>]

Hi,

because we lately had problems with low loading
times of the GIMP help docs, I've set up a performance monitoring
job at Jenkins:
https://build.gimp.org/job/_infra-monitor-docs/

It downloads the help index file for each help language
and averages the loading times.
The time limits to mark a build as ok, unstable or failing are:
Up to 1 second: ok,
1 to 9 seconds: unstable,
10 seconds and more: failing.

For more information on these time limits see Jakob Nielsen's
article 'Response Times: The 3 Important Limits'
(http://www.nngroup.com/articles/response-times-3-important-limits/).

Kind regards

Sven
