Performance Tuning

[robi]

Here's a thread on performance tuning Cloudron, App containers and the Apps.

As I've already collected several tweaks and improvements for my systems, I'll be posting them in this thread. You're encouraged to do the same.

Hopefully this allows us to test and get feedback on tweaks to add to the default Cloudron installs.

Did you find any noticeable performance improvement by setting that property? I'm looking into fine-tuning my Ubuntu image.

Best to try on smaller ones.
