Hello all,

Skanlite is very very slw through LAN connection, it freezes approx. 1
minute at each UI change (changing a parameter through the UI like opening a
scrolling menu, change tab...). Sometimes, it crashes completely.

Note that Skanlite works perfectly through USB. 

I can use Simple-Scan instead, which works perfectly with LAN connection, but I
would prefer Skanlite because of its advanced functions.

I don't know what information or log you need to investigate, I keep this
thread open in my browser to answer quite quickly.

My Hardware (even I don't think it is the cause) : Canon MG3650, connected on a
Raspberry Pi, which works perfectly on all configurations (Linux & Windows),
excepting Skanlite over LAN.

Thanks for your help ! ;)

I disagree, pixma network backend works perfectly with simple-scan !

OK, I apologize, I didn't understand that way.
I hope it will solve the problem ! ;)
Thank you !
