Hi!  
I hope this is the right place to ask my my question, otherwise, please  
let  
me know where i can ask…

I’m playing with rtl\_tcp since 2 yrs (or more…), but very very very  
often  
(almost always), when i connect to rtl\_tcp with ANY program like  
sdrsharp,gqrx,and so on, i get this in the console:

“ll+, now 1”  
“ll+, now 2”  
“ll+, now 3”  
…  
“ll+, now 461”  
“ll+, now 2”  
“ll+, now 3”  
“ll+, now 4”

and the client is sometime very slow…  
Using direct usb dongle the problem disappear.

Tested on local connection on a very fast pc, tested on a raspberry and  
tested on 127.0.0.1

What can it be?

Many thanks for your patience!
