slow first page loading, occasional rebooting of LM

[chrigi]

i recently rebuilt more ore less the same visualization of our private house in the new visu. a nice step forward with some very convenient features. 
however, there are some struggles and i don't know, what exactly the reason is and where to post it.
project data:
- 2300 objects
- 4-6 clients (tablets)
- many trends, total 13.7 mb
- resident scripts, some of them CPU consuming
- TP load 20 - 40%
- typical CPU load: 0.9 - 1.3 %, memory since new visu about 70%
LM 5 lite, iMX6, actual firmware version

observations: 
- opening new visu takes aprox. 20 s. CPU usage goes up during this period and other clients can become less responsive
- leads occasionally to reboot (overload)

proably unrelated: trends occasionally stop recording, showing the same values. stopping occurs either at 12:00 or at 0:00.
according to a table in the forum my trends are saved twice a day. 
-> memory problem ? 
dont want to switch to the new visu before i know that it wil run stable. (my LM did not reboot in ages before). 
suggestions ?
thanks

Looks like your CPU is overloaded, install system load app to check which process is consuming most.

the screenshot is with all the normal scripts active. when i deactivate script 123, loading the new visu for the first time still takes 18 seconds.
after loading the new visu works fine and is responsive. during building the new visu, i deactivated script 123 to save CPU power. ist was more reliable but i still had some restarts.
