It seems like you are confusing two pieces of software: There is Baloo, which is the KDE file indexer. And then there is Akonadi, which is the storage service for all PIM related things (so emails, contacts, calendars etc.). If you disabled Baloo in the settings it should not show up as a process anymore and certainly shouldn't be using any system resources.
Akonadi is required for the usage of KMail, KOrganizer and such (because they use it to store their data, so that is rather essential). If you don't use those applications, you can simply remove it with your package manager. Otherwise we'd appreciate a bug report with regards to the high CPU / memory usage on bugs.kde.org. Thank you for using KDE software :)

Oh right, seeing those Gio in my ~/.local/share/akonadi, I was supposing that it was for file indexing and that was somehow the storage for Baloo or something like that.
I haven't investigated more than that as I don't want to spend too much time on it and just killing Akonadi server from its console is enough (the downside is that after killing it I can't use KMail anymore, which otherwise is a really great MUA).
So maybe it has something to do with my email settings then? I'll try to find time to investigate and check if I haven't activated anything like offline storage, otherwise I'll create a bug report.
Anyway thanks for the great work over the years, beside this little issue, KDE works flawlessly and I like to be able to customize just what I need when I need.
