[1.6][SOLVED] high cpu load on windows when using certain packages

After updating my project from 1.5.x to the current version I got a very high cpu load all the time and I’m not able to work with this version. I found out this high cpu usage is caused by some packages but I don’t know why.

To reproduce:

meteor create test
cd test

Now I can see node.exe*32 is using between 5 and 10 percent of the cpu.

meteor add rajit:bootstrap3-datepicker tap:i18n

After installing these packages I got betweeb 15 and 30 percent cpu load. It seems that a lot of other packages listed in my packages file don’t cause this effect.

After reading this https://github.com/meteor/meteor/issues/9175 I found out that I set METEOR_WATCH_POLLING_INTERVAL_MS=750 a long time ago. After unsetting the variable it got much better.
