Enables performance optimization of an application on a machine with nonuniform memory architecture (NUMA) by increasing the application's use of lower latency memory. By default, this option is disabled and no optimization for NUMA is made. The option is only available when the parallel garbage ...
However, profilers can dramatically simplify monitoring the memory footprint on a working application. The first giveaway is that the used memory monotonically increases over time. This isn’t always a sign of a memory leak. However, on an application like ours, increasing memory usage might be ...
Java Garbage Collection Tuningshould be the last option you should use for increasing the throughput of your application and only when you see a drop in performance because of longer GC timings causing application timeout. If you seejava.lang.OutOfMemoryError: PermGen spaceerrors in logs, then ...
We’ve already established that monitoring memory usage is critical to ensure your Java application runs smoothly. Consequently, heap dumps can help diagnose issues such as memory leaks, GC problems, and java.lang.OutOfMemoryError, and optimize memory usage. You can load the heap dump file into...
Figure 1: The Memory tab shows increasing memory usage, which is an indication of a possible memory leak. You can also use thejstatcommand to monitor the memory usage and garbage collection statistics as follows: $ <JDK>/bin/jstat -gcutil <pid> <interval> <count> ...
Since Young generation keeps short-lived objects, Minor GC is very fast and the application doesn’t get affected by this. However Major GC takes longer time because it checks all the live objects. Major GC should be minimized because it will make your application unresponsive for the garbage ...
Releases the given number of permits, increasing the number of available permits by that amount. If any threads are trying to acquire permits, then one thread is selected and given the permits that were just released. If the number of available permits satisfies that thread's request then that...
Increasing the number of buckets ("rehashing") may be fairly expensive, so it pays to create identity hash maps with a sufficiently large expected maximum size. On the other hand, iteration over collection views requires time proportional to the number of buckets in the hash table, so it ...
