1370 * Maximum number of SYN_RECV sockets in queue per LISTEN socket.
1371 * One SYN_RECV socket costs about 80bytes on a 32bit machine.
1372 * It would be better to replace it with a global counter for all sockets
1373 * but then some measure against one socket starving all other sockets
1374 * would be needed.
1375 *
1376 * It was 128 by default. Experiments with real servers show, that
1377 * it is absolutely not enough even at 100conn/sec. 256 cures most
1378 * of problems. This value is adjusted to 128 for very small machines
1379 * (<=32Mb of memory) and to 1024 on normal or better ones (>=256Mb).
1380 * Further increasing requires to change hash table size.
