As time passed, available memory increased faster than number of concurrent tcp sockets. As a result, a machine with 4GB of ram gets a hash table with 524288 slots, using 8388608 bytes of memory. Lets change that by a 16x factor (one slot for 128 KB of ram) Even if a small machine needs a _lot_ of sockets, tcp lookups are now very efficient, using one cache line per socket.
