Bug ID: 57114
Summary: Performance : Functions that only have values as
instance variable should not synchronize execute
Product: JMeter
Version: Nightly (Please specify date)
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Main
Assignee: [email protected]
Reporter: [email protected]
As per Ubik Load Pack report:
-----------------------------------------------------------------------------
Reviewing code of Functions in JMeter we don't understand why Functions that
only have values as instance variable (so Beanshell or StringFromFile or
IterationCounter (which could be improved to avoid it) are not concerned)
synchronize on execute.
It appears "values" instance variable is initialized within
StandardJMeterEngine thread and then only accessed in read mode by JMeterThread
But it is true that if synchronized is removed then CompoundVariable is
accessed by multi threads but it seems it uses thread related data so it should
be OK.
