Energy impact of Safari is extremely high on my Macbook Air Mid 2013 El Captian 10.11.2. It lead to high usage of CPU (Temperature ~65.0°C) and the CPU fan is running in full speed (6500.0 RPM) constantly.

I have tried so far:

  1. Clear all Safari cached
  2. Restart laptop
  3. Remove/disable all extensions
  4. Uninstall all the software that might possibly affecting e.g. Anti-Virus

The issue is only happening in Safari. Chrome and Firefox are both OK.

Thanks for helping in advance!
