> Johannes, could you point to or send the code that would turn off Nagle's algorithm on the Java side?

It's attached in my original message as a patch. But also in this one now ;)

Cheers,

Subject: [PATCH 1/2] Allow to set tcp nodelay flag

Add a method that allows to toggle the tcp nodelay flag on the socket
used by SpreadConnection. If enabled, small messages are not accumulated
to bigger chunks and hence sent immediately, which prevents unwanted
delays.
