I've owned a BQ Aquaris E4.5 and I now own a Meizu MX4 Ubuntu edition, and on both device, whatever the channel (I tried the stable, the rc-proposed and the devel-proposed) and Ubuntu-touch seems slow, notably when switching from a scope to another one.

Is there any schedule to optimize, or find the root cause of that "problem"?

You might want to change the swappines. On my Aquarius M10 it is set to 100% by default. If you want to know what swappiness is and why it can make things slower read this: https://en.wikipedia.org/wiki/Swappiness.

To change swappiness you must install the terminal app from the software center, then enter the folowing commands.

sudo su
mount -o remount,rw /
bash -c "echo 'vm.swappiness = 30' >> /etc/sysctl.conf"
cat /proc/sys/vm/swappiness

Restart your device. (yay)

If the last command doesn't return 30 then try this:

nano /etc/sysctl.conf

Once you enter this command you will enter a text editor. You will see 10 black dots on an orange box in the shape of a key pad. Tap and hold that box and a menu should pop up, select the option that says "SCR". You will see some arrow keys above your keyboard, use them to navigate the text file look for a line that says: vm.swappiness = some number if you don't find it just add it. Replace some number with 30. Now you want to save the file by taping and holding the orange dots from before, and selecting "nano". you will see some options appear above your keyboard. Tap "ctrl+o" then "ctrl+x". Restart your device.
