While in AC power, if I copy a number of files in my laptop from another device, after few minutes the laptop nearly hangs and have to wait for a long time for it to become normal. When I close baloo in the meantime then the laptop comes back to normal again. I do not see this problem when the laptop is running on battery power (guess baloo was not indexing in battery power).

Copy about 100-300 mb data files from external source 2. Wait for few minutes in AC power 3. Plasma freezes 4.

What kind of files were these 200-300 mb of files?
(In reply to Vishesh Handa from comment #1) > What kind of files were these 200-300 mb of files? Text files (mainly codes, compiled .mod .o files)
We consume a lot less disk IO now.
After installing kubuntu-desktop on my Ubuntu 15.10 installation, I updated to 16.04 today. I noticed a lot of lag in KDE especially when clicking to open new windows. Tried killing the baloo process and then system was back to normal. Is this related to this bug?
