The Java(TM) SE Performance Tuning course provides students with the knowledge and skills required to monitor, profile and tune the performance of Java(TM) 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.Students who can benefit from this course:Java(TM) technology application developers, consultants, architects, and system administrators who are interested in improving the performance of Java technology applicationsThis course counts towards the Hands-on course requirement for the Java SE 6 Developer Certification. Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on Requirement.
