Tuning the HotSpot JVM's Garbage Collectors
|
The HotSpot JVM has been refined and revised with every release of
the JDK since the advent of Java in the mid 90ies. Today, Java developers
face an abundance of GC algorithms - from plain and simple serial stop-the-world
collectors with a single reaper thread to highly parallelized collectors
that run several GC threads concurrently with application threads. Each
of these collectors can be configured and tuned in various ways in order
to control pause times or increase throughput. The number of choices a
Java developer has for configuring the JVM:s garbage collection for his
application is overwhelming. Hence, garbage collector tuning for the SUN/Oracle
JVM is a daunting task.
The talk aims to shed light onto the garbage collection strategies in
the Sun/Oracle JVM by explaining all algorithms (including Java 7's Garbage-First
collector) and discussing strategies for tuning and configuration of the
various collectors.
