TDE vs Plasma 5 boot time

Hi all, I am currently running Plasma 5 (KDE 5) on my desktop computer, and I find that Plasma 5 is capable of booting, from login to desktop, faster than TDE on the same machine. This computer is an humble Core 2 duo with 2gb of ram, probably from 2008 or so. While this is great for KDE, it is not that great for TDE, because KDE is built on much heavier toolkit and frameworks than TDE. And TDE (with its KDE 3 past) was built to run well on P2-P3 computers. The thing is that even with much faster computers, it should have near instant boot time. So, I don't know if there could be ways to re-organize TDE startup sequence, or maybe to prefetch so things in TDM. Maybe starting TDE modules in parallel could help? May 2016 be a great year for you all! -Alexandre
