Eclipse slow text file opening

Question

I have had this before and after switching computers and a long time of happy developing, I'm having it again: Eclipse taking extremely long to open simple text files.

What's happening, what's changed is:

• Tomcat now requires frequent restarts / reloads even changing Javascript files
• text files take at least 30 seconds to open

My environment is:

• Mac OS Maverick
• STS 3.4.0
• Sysdeo Tomcat
• Maven project nature
• AspectJ capability
• Android development tools
• Gradle IDE

I realize that reinstalling Eclipse/STS would be an option, but in stead of taken half a day to get it just right again, I would prefer to just fix the problem. Any ideas?

Is there any way to trace where eclipse is spending its time, some kind of high level debug output?

Answer 1

Well, after removing *.js from the file associations, the problem seemed to go away. After that I readded it again and everything was good again. Thanks @Cristophe for pointing me in the right direction
