New Revision: 1615465

URL: http://svn.apache.org/r1615465
Log:
Migrate Log4jInitPerformance to log4j-perf.

  - Part of LOG4J2-761 (no specific sub-task as this one was rather trivial).

Added:
    logging/log4j/log4j2/trunk/log4j-perf/src/main/java/org/apache/logging/log4j/perf/jmh/ConfiguratorInitializeBenchmark.java
Removed:
    logging/log4j/log4j2/trunk/log4j-core/src/test/java/org/apache/logging/log4j/Log4jInitPerformance.java

Added: logging/log4j/log4j2/trunk/log4j-perf/src/main/java/org/apache/logging/log4j/perf/jmh/ConfiguratorInitializeBenchmark.java
URL: http://svn.apache.org/viewvc/logging/log4j/log4j2/trunk/log4j-perf/src/main/java/org/apache/logging/log4j/perf/jmh/ConfiguratorInitializeBenchmark.java?rev=1615465&view=auto
