##Introduction to optimizer for eclipse

Official website: http://zeroturnaround.com/free/optimizer-for-eclipse/

As the name suggests, optimizer for eclipse plug-in is mainly used to solve the problem of eclipse performance optimization

###1. Low memory allocation

A lower minimum heap size will cause the JVM to allocate additional memory. When you don’t have enough memory, the JVM with frequent garbage collection will slow down your experience

###2. Slow class verification

Class executes validation classes and plug-in classes in eclipse, which significantly slows down the startup of the JVM

###3. Big index and history

Over time, eclipse generates a huge cache of history and index files. These files in RAM and SSD hard disk make eclipse slow and unresponsive
