Hi Itamar,
once again Twisted surprises me: it just works!
I have tested a master/child combo over pipe (both Twisted) with a push
producer on the sending leg.
It can push around 70MB/s raw binary (16k write size) to the child. Load is
evenly on 2 CPU cores each at 80% and stays roughly consta

Hi,
I don't know the answer to your question...
I've been thinking about flow control lately.
I recently wrote a little working prototype VPN in Twisted using
IPushProducer and IConsumer interfaces
but I have not yet implemented flow control :
Here we can see how I proxy between TUN and UDP usin
Hi,
with TCP (either remote or loopback) I can have flow-control using the
producer-consumer machinery that Twisted provides.
Is that (flow-control / producer-consumer) also available (and practically
usable/recommended) with:
a) Unix Domain sockets
b) Pipes (spawnProcess)
?
Thanks!

ahh, I felt I missed sth;) thx .. I'll look into that

Transports provide the IConsumer interface, to which you can hoo

For a test driver for a TCP-based protocol (written in Twisted) I want to send
data to a
receiver as fast as the receiver can consume data, but not faster.
Apparently, a naive loop which just does transport.write() does not work. When
I do
reactor.select(0) between the writes, it somehow works,
