I'll be back to give you some feedback
For the language, it's OK, I had forgotten to put SQL in Language Method, sorry, i upgrade to svn 3905 and i did mysql upgrade_2.14.sql
I've noticed an improvement, I don't seem to have any more ERROR 503, the icons load a little bit faster, but when an agent first connects to a new workstation, there are always 1 or 2 broken icons (LIVE CALL icon, or one of the webphone icons), after refresh 1 or max 2 times, it's OK. For example, look at my home page
https://apisnix-crm.com, which I've customised, it always displayed fine before but I'm sure you'll have to refresh to see it properly
yet in top, htop or reports web vicidial, I don't even use 5% of the system
