#17028 closed enhancement (fixed)

[Patch] Improve performance of some validator tests

Reported by: GerdP Owned by: team
Priority: normal Milestone: 18.11
Component: Core validator Version:
Keywords: template_report Cc:

Description

What steps will reproduce the problem?

  1. Run validator on a download of a small city
  2. Wonder why "ConditionalKeys" takes so long

What is the expected result?

Quick test because only a few objects have conditional keys

What happens instead?

Test needs > 2 secs

Please provide any additional information below. Attach a screenshot if possible.

The simple patch avoids some calculations for all the objects without any tags, like most nodes
and thus reduces run time.
Same for OpeningHours.

Hm, this doesn't have the expected effect. Seems that the JIT confused me. When you execute the validator for the first time
the ConditionalKeys still takes long, further executions are faster.
I see something like 2.8 secs -> 1.2 secs -> 0.8 secs -> 0.5 secs -> 0.4 secs.
So, what we see here is probably JIT in action. Sorry for the noise.
