Java – can we choose which plug-ins to load in eclipse at startup?

I'm working on different technologies and frameworks I write:

>Web applications using GWT, hibernate and aptana studios. > Android app. > Ruby on rails web application using aptana studio

At present, I separate projects in different workspaces, but my eclipse becomes fat, which consumes so much memory (it can reach 700MB) I thought about installing it separately, but it doesn't seem practical. It will consume a lot of space

I appreciate your answer

Editor: Thank you Through maxym and zvikico's answers to this question, I can set up my workspace more correctly

Solution

go

Window > Preferences > General > Startup and Shutdown

Here you will see "plug ins activated at startup", so you can check / uncheck them
