Reflection Probe Baking Times Taking Up To 88 Times Longer From 5.1.4 to 5.3.1!

Hi everyone, just wanting to let you know of my findings regarding the reflection probe baking part in minutes and seconds from Unity 5.1.4 to 5.3.1 that is now taking much longer to complete. This is slower in general and even further exaggerated if you are using ETC2 texture override on the Build Settings and Android platform.I have submitted a bug for this (bug number 763103):

This is using a super simple scene with one default setting reflection probe at 128 resolution, one directional light and 5 planes with the default white material using the standard shader. With a scene with several reflection probes the time gets multiplied, some scenes with 15 probes take well over an hour to complete just the reflection probe bake.

Just the Reflection Probe Part Baking Times (Test Machine Using i7 5820K with 32GB RAM):
Unity 5.1.4 ETC2 Android: 4 Seconds
Unity 5.1.4 Don't Override Android: 4 Seconds

Unity 5.3.1 ETC2 Android: 5 Minutes 55 Seconds
Unity 5.3.1 Don't Override Android: 59 Seconds
