How to improve the running speed of myeclipse/eclipse

Do Java development generally use MyEclipse or eclipse,myeclipse is a huge memory of the big guy, recommend the machine at least 2G memory, otherwise it will be very card, To reduce its memory consumption, you can do the following simple setup (Eclipse wants to increase speed or you can press this setting).
1, remove modules that do not need to be loaded
Windows->preferences->general->startup and Shutdown
At this point, the module that is loaded at eclipse startup is displayed on the right. According to the actual need to remove some modules
such as:
WTP: A similar thing to MyEclipse, the main difference is that WTP is free, if the use of myeclipse, this can be canceled.
Derby: A database saved as a jar
a large row of MyEclipse Easie start items: MyEclipse supported servers, select only their own, other cancellation, such as I only selected TOMCAT6,GLASSFISH2
br>
2, canceling myeclipse automatically validating project profiles at startup
MyEclipse automatically validates the configuration file for each project at startup by default, which is a time-consuming process,
You can select in the Preferences window Myeclipse–> Validation, and then in the Validator list on the right, only the Manual items are reserved (Manual column is all checked, bulid column leaves only the first item classpath dependency )。
Just select the file if you need to verify it, and then right-click to select Myeclipse–run validation.
Manual authentication method:
On the file to be validated, right-click –>myeclipse–>run validation

3. Remove spelling mistakes

When the spell check is turned on, when the method name is the abbreviation of the word, he will also suggest that the error, preferably removed, is not much useful:
Windows–>perferences–>general–>editors->text editors->spelling
Select the Enable spell checking check box

4, the default JSP editor to MyEclipse JSP Editor (recommended speed is slow)

The original default JSP editor is myeclipse Visual JSP Designer, as the name suggests, this compiler is a JSP visual editor, for beginners have a lot of help, but modify this default editor can actually improve the startup speed
Windows–>perferences–>general–>editors->file Associations
Find * In the file types on the right. JSP, set the MyEclipse JSP editor under associated editors to default

5. Turn off Automatic Updates

5.1, turn off MAVEN Automatic Update:
Window-preferences->myeclipse->maven4myeclipse->maven
Turns off all download and update options in the right window, a total of four items (remove the previous tick)
5.2. Turn off update schedule
Window–> preferences–> general–> Startup and shutdown–> Automatic Updates (remove front tick)
5.3, window–> preferences–>startup–>show myeclipse Dashboard on Startup (tick)
