It gives 12.0 MB/s Linrad does not work above about 0.8 MB/s on a single socket. It seems I will have to check the Linrad code;-) The sendto call does not block. Not surprising since I write at 10 times below max speed. A call to select always tells me that write will be OK. Each packet has a number so I can see which ones are lost. While running one slave in the same computer and another one on a different computer I can see lost packages like this: lost on lost on the same another computer computer 517 523 583 1449 619 1874 640 - 706 772 833 899 935 Packages tested: 487 to 3195. It is obvious I have a problem in the receive thread! (a very small routine) Knowing that it was not hard to find!! Thanks fo the help:-) 73 Leif ############################################################# This message is sent to you because you are subscribed to the mailing list <linrad@antennspecialisten.se>.
