Java SE Performance Tuning (SEM-DTJ-380)

Email Product Description

The Java SE Performance Tuning course provides students with the knowledge and skills required to monitor, profile and tune the performance of Java technology applications. This course takes a holistic approach to performance tuning. Students will learn to collect and interpret performance data by monitoring and profiling all levels of the software stack beginning at the operating system level and continuing through the Java Virtual Machine to the application level. The course also examines performance tuning as it relates to the use of 64 bit JVMs and multi-core platforms.
