Eclipse too slow and unresponsive

Question

i use EMF framework, Sirius, Acceleo for a new eclipse plugin me and my team mate is working on. The problem is, everytime i want to try and run the plugin we already developed, eclipse took way too long to start, iam not talking about 30 second or 4 menutes long, it literally takes 3 hour more just to start, is there any way to fix thi or to fasten up the process without uninstaling all the plugin i need(Sirius, Acceleo, EMF), this issue happen after i download acceleo and Sirius to be used in developing my app
