Let me make it clear that I'm NOT having any problems with latency, but I'd like to keep it as low as possible...so I'm asking (after not finding a good answer using search)

If the network latency/overhead from using udpsend any greater than the latency between m4l devices using regular send?

I have my suspicions, but without a real measurement there's not really any point.

If I wanted to set up some devices to measure this, (in general terms) how should I go about it?

has-anyone-measured-the-sendreceive-latency-between-devices

the problem with send device is that latency is un-expected.

from what i gather something to do with multi-core processors

and different "levels" creating different latency's.

but i cant tell you that i'm using the plugsend~ device

and that the latency is very minimal. i can scratch into a muted track

with plugsend~ on and monitor my scratching on the plugreceive~ channel

and it will still be responsive enough to scratch.

I understand what you mean, but I'm talking about the general send/receive and udpsend/receive. It's not audio data, it's midi.

I *am* happy your latency is low enough for scratching though. :)

I've measured the latency of send/receive and udpsend/udpreceive with [cpuclock].

In both cases it seems directly proportional to Live's audio buffer size, ie.

Apparently the transmission is handled by buffering in sync with the audio buffer.

Has anyone measured the send/receive latency between devices?
