Eclipse saving workbench state hangs

I followed the below instructions in the blog

Make a backup of your “.metadata“-folder (very important!!) (this folder inside teh eclipse workbench/workspace folder)

navigate into the “.plugins“-folder located inside “.metadata“

delete the folder “org.eclipse.ui.workbench“

startup eclipse again and check if there is still everything you need

and the problem was resolved , now when I close my eclipse it doesn't hang at saving workbench state.

infact I have noticed that the eclipse is starting a closing faster than before.
