Bug ID: 57145
Summary: RandomController : Use ThreadLocalRandom instead of
Random for better performances
Product: JMeter
Version: 2.11
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Main
Assignee: [email protected]
Reporter: [email protected]
As per javadoc:
http://docs.oracle.com/javase/7/docs/api/java/util/Random.html
"Instances of java.util.Random are threadsafe. However, the concurrent use of
the same java.util.Random instance across threads may encounter contention and
consequent poor performance. Consider instead using ThreadLocalRandom in
multithreaded designs."
As we need to support Java6, I will be using Doug Lea class which is under
