Hey @remolacha ,  
I am having the same issues as you have faced.  
Have you found any fix to resolve the problem.

My installation is as follows  
Client device: 55 laptop (Acer Aspire A515-51 -\> core i3 7th gen with 4gb of RAM)  
Server device: 1 desktop (Acer Aspire Veriton -\> core i5 6th gen with 4gb RAM and 1TB HDD)  
Router: Tenda AC15(all device connected on 5ghz network)  
Kalite: 0.17.4 with almost 110GB English content  
OS: Ubuntu 16.04 (on the server device), win10 (on client device)

imho, i don’t think there is any hardware or network bottleneck in my setup.  
Because when all the user just wants to login at the same time (which is typical at classroom environment) kalite isn’t even accessible(i mean it takes 3-5 min just to login) in main device where its installed. The CPU is idling at 20-30% and 1.5-2gb of RAM is occupied when at peak load.  
@benjamin can you please direct me to a link where can find some tweaks that you are mentioning.
