[samigo-team] Performance testing and Samigo 2.9

[Stephen Marquard]

Hi all,

We have been doing some performance and load testing of T&Q for large
assessments (160 and 400 questions) with JMeter, and have identified one
specific issue which is that in 2.8, the response time per item
submission increases as the test progresses (e.g. submitting answer to
Q1 could take 100ms but for Q160 the response time is 500ms).

The good news is that this behaviour is no longer present in 2.9 and
trunk - the response time is the same no matter where you are in the
test.

So two followup questions:

1. Is anyone aware of a specific JIRA / code change between 2.8 and 2.9
that would have fixed this issue? (As if so, we would consider merging
this to a local 2-8-x branch).

2. How much testing has the 2.9 T&Q release candidate had, and would
you consider it ready to run in production?

Regards
Stephen
