I'm in the process of upgrading my web/database/nfs/jack-of-all-trades box from 6.2 to RELENG_7. I figured now would be a good time to clean up my kernel config files. I have the following in my old kernel config: # Statically Link in accept filters options ACCEPT_FILTER_DATA options ACCEPT_FILTER_HTTP # Zero copy sockets support. This enables "zero copy" for sending and # receiving data via a socket. The send side works for any type of NIC, # the receive side only works for NICs that support MTUs greater than the # page size of your architecture and that support header splitting. See # zero_copy(9) for more details. options ZERO_COPY_SOCKETS Are these options still working/recommended? With all the changes to networking over the years (this box was originally set up during the 4.x days and has been upgraded many times) I have no idea if these are still good things to have. Thanks! -Jon
