I'm making some tests to see what the max_value can be for the rcv_cc for soreserve and it seems that 256 KB (I may be way too optimistic) is too big and 128 KB is OK. There seems to be a limit from what I can see in the source code of sbreserve but finding this limit is not that easy following the source. Another point is that there's a sysctl for the net.inet.raw.recvspace which is said to be 8192. Does someone know the MAX limit for the recv buff size of soreserve? _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
