The stock ROMs are shipped with a huge amount of bloatware, from which I see many processes active when opening a task manager. Let's freeze/disable or uninstall crap we don't need
You can disable many apps without root from Android's app manager, but you'll need root for many of them. Root is mandatory to uninstall system apps.
You can use this spreadsheet (of moly82) on the new tab named jelbo. I'm collaborating with moly82's generic Xperia Lollipop debloating script. Turns out the Z4 Tablet does have quite some things moved around / added / removed, so it's definitely good to have added support for it. New sheet contains both generic Xperia stuff and Z4 Tablet specific apps. The jelbo tab contains both my findings and the ones from moly82.
In the spreadsheet is a list of all the pre-installed unneeded system apps either I or moly82 has 'frozen' or disabled, without any problems. I've marked some yellow because you might need the functionality, for example DLNA or native Exchange support. It's not finished yet, but you can go ahead and use it as a base of your decisions to freeze/uninstall stuff.
You can debloat manually with apps like Titanium Backup. Here's a procedure to make a label, associate apps to it and batch freeze or uninstall them.
For anyone wanting to collaborate, send me a PM with your e-mail address and I'll give you edit-rights.
Eventually, when this thing is 'done' I plan to either expand moly82's script or at least share my Titanium Backup 'custom' database with the labeled categories, for easy batch actions.

- Get Titanium Backup and start it. You probably need Pro.
- Go to the tab named Backup/Restore.
- Tap 'Click to edit filters' in the top right.
- Tap 'Clear' in the top right.
- Tap 'Create label ...' in the bottom right.
- Type a name, give a color (optional) and tap 'Add/Remove elements ...'
- Check the boxes of apps you wish to free or uninstall (based on the spreadsheet for example).
- Tap the green checkmark on the top right.
- Tap 'Save'.
- Back in th Filters section, make sure no filter is active (tap 'Clear'), select the newly created label (check the box) and tap the green checkmark.
- Titanium Backup will display a list of the apps you've labeled.
- Tap the 'file and checkmark' icon top right to get to the 'Batch actions' screen.
- Scroll to 'Freeze / Defrost' and tap the RUN button next to 'Freeze all user & system apps (USE FILTERS & EXTREME CAUTION)'.
- Profit.
