-H MaxFD set max number of file descriptors/handles

Max number of sockets is 2048/8192 for 16bit/32bit TCP/IP stack.

Number of file descriptors/handles includes sockets, file handles and
pipe handles.
One descriptor use 176/180 bytes without/with delay pools 

Default number of descriptors is 2048/8192 for 16bit/32bit TCP/IP stack 
so you can save about 300K/1400K with "-H 256" 
256  descriptors is enough for home use as well for local net with 
about 30-50 non too active users.
