[hibernate-dev] [HV] Hibernate Validator 6 benchmark updates

Fri Jul 21 12:47:56 EDT 2017

Hi,

(Not a big fan of HTML emails but I gave up with formatting the table,
sorry)

So I took the time to revisit the old BVal benchmark [1] and posted an
updated version of it here: https://github.com/gsmet/
beanvalidation-benchmark.

I pushed a few more commits to optimize the parsing/metadata building phase
here: https://github.com/hibernate/hibernate-validator/pull/814.

Note that the benchmark is much more representative that our very simple
JMH tests: it generates a lot of bean definitions with constraints on
properties and getters (we were really bad on getters) that are more in
line with real life situations.

The *checkRawValidationSpeed* bench only evaluates the validation
performances while the *checkRawParsingSpeed* test only evaluates the
parsing and metadata building phase (so clearly not realistic but it's a
good way to exercise and optimize this part).

Results below.

TLDR :

   - *Validation*: 6 as of my branch is ~ 2 times faster than BVal 1.1.2
   and HV 5.4.1.Final
   - *Parsing/Metadata building*
      - 6.0.0.CR3: we had quite a regression here, it's ~ 2 times slower
      than 5.4.1.Final
      - as of my branch, we are still a little slower than BVal but faster
      than 5.4.1.Final

*checkRawValidationSpeed* tester.repetitions=1000
in ms, lower is better
