Update of /cvs-repository/Packages/ZEO/zrpc
In directory cvs.zope.org:/tmp/cvs-serv19728/zrpc

Modified Files:
	server.py client.py 
Log Message:
turn on TCP_NODELAY, in both directions. This avoids latency when a request or response doesnt fit in one packet. ZEO is already doing its best to buffer data before calling send, so TCP_NODELAY can do little harm
