问题
I am using Spring 3.7.3.RELEASE on MacBook Pro Retina with 128GB SSD. While doing any kind of operations like saving the changes, refreshing the project, building the project, while debugging, while synching with VCS etc, it becomes so slow. I have already did the following things,
Unchecked all plugins in Windows -> Preferences -> General -> Startup and Shutdown except spring maven integration tool
Disabled automatic builds under Install/updated and Label Decorator
Upgraded to the latest JVM
Disabled all validations
My laptop configuration:
Model Name: MacBook Pro
Model Identifier: MacBookPro12,1
Processor Name: Intel Core i5
Processor Speed: 2.7 GHz
Number of Processors: 1
Total Number of Cores: 2
Memory: 8 GB
Storage: 128GB SSD
STS configuration:
-clean
-startup
../Eclipse/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
../Eclipse/plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.300.v20150602-1417
-product
org.springsource.sts.ide
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms512m
-XX:MaxPermSize=6000m
-Xverify:none
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Xdock:icon=../Resources/sts.icns
-Xmx6000m
Please suggest me what to do to speed up STS.
回答1:
I had faced this issue in past, but after installing Optimizer for Eclipse it become much faster. Otherwise you can use the latest version of Eclipse i.e 4.6 for STS it is slightly faster than the previous one and the thread blocking issue is solved here.

Optimizer is definitely helpful but I also disabled almost all validation except for few essential ones
Click Window > Preferences and select Validation in the left pane. The Validation page of the Preferences window lists the validators available in your project and their settings.
To disable individual validators, clear the check boxes next to each validator that you want to disable. Each validator has a check box to specify whether it is enabled for manual validation or on a build.
