[Zodb-checkins] CVS: ZODB3/ZEO/zrpc - server.py:1.8.20.2 client.py:1.25.16.4

[Jeremy Hylton]

Update of /cvs-repository/ZODB3/ZEO/zrpc
In directory cvs.zope.org:/tmp/cvs-serv31430

Modified Files:
      Tag: Zope-2_7-branch
	server.py client.py 
Log Message:
Disable TCP_NODELAY.

Disable TCP mechanism that attempts to reduce the number of small
packets, by delaying small packets in hopes of accumulating more data
into a single larger packet.  This feature interacts poorly with an
RPC protocol like zrpc, because it sends a small packet and then waits
for a response.  zrpc will not accumulate any more data, because it is
waiting for a response.
