a connection uses about 112 bytes (forget exactly what). 
Ignoring memory taken by the kernel, apps etc, you can have 
2G/112 simultaneous connections.

Changing the number of buckets doesn't change the number of 
connnections that can be stored, only the number of buckets 
in which they're stored.
