When I do a sendmsg() or sendto() on a datagramsocket, the system CPU-time increases by a factor of ten, on several computers, if I write to a broadcast address instead of to a single address. I did ask permission to broadcast on the socket. Does anyone have an idea why broadcasting is about 10 times as slow, and maybe know a method to broadcast without so much overhead? -- Peter Mutsaers email: muts@fysaj.fys.ruu.nl Rijksuniversiteit Utrecht nmutsaer@ruunsa.fys.ruu.nl Princetonplein 5 tel: (+31)-(0)30-534504 3584 CG Utrecht, Netherlands
