I have read some stuff about JSON IPC/RPC, Kodi 17 used to have suppoort for RPC API V8, Kodi 18 works with RPC API V9, so it could be some missing stuff and it could be causing the low performance.

Another thing is that KODI 18 dont use TCP9090  anymore, so all the comunications by now are made throu HTTP on TCP 8080, using WebSockets
