Re: [boost] [serialization] Archive reuse

I would guess its possible but I don't know for sure that's were any
performance bottleneck is.  The new version of native binary archive
uses streambuf i/o instead of basic_stream i/o which should be
noticibly faster since it does use a mutex lock on each i/o.  That
might help.

Initalizing an archive basically just consists of writing a small header
you might try using no_header on construction to see if that helps.

You might try reusing the stream and just create a new archive- that
might help.

You might create a custom variation of a standard stream buf which
maps to sending UDP packets.

You might make your own version of native_binary which doesn't
use a stream but uses some faster way if setting up to send UDP
packets.

Good Luck
