max osc networking

is there a theoretical limit to the volume of OSC messages that an OSC network can process simultaneously? im building a max4live program that relies heavily on 'send' and 'recieve' objects between devices, and im trying to determine if these s & r objects should be replaced with sn OSC network.

which route would be the most process-friendly?
how many messages would be considered a limit?

Re: max osc networking

as far as I know the only limit should be what your computer can process without choking.

I'm no expert though, so take that with a grain of salt.

Re: max osc networking

right now i'm sending around 400 messages, being recieved in about 600 different locations. generally, it seems the messaging is fluid an not latent, however, in some instances when a mass influx of messages are triggered at the same moment in time, the latency gremlin starts to poke its ugly head.

this is with send and return objects, btw
and, using a late 2010 mbp 2.4ghz c2d 8gb ram
think a ssd drive would help latency or buffer issues?

Re: max osc networking

I don't use Max. But I understand that the purpose of OSC is to send messages between different applications, so for me that means communicating between multiple instances of Pd in order to take advantage of multi-core processors.

My gut level feeling is that if you are within one application you should use send/receive as that is it's intended purpose. You are experiencing latency because that's a helluvalot of messages to send at once! Perhaps there's an object that can delay messages so that they are not all piled into one cycle of the message processing rate (look up control rate or message rate and see what advice there is out there) Or this can be solved by using a faster computer (duh, read: rack mount desktop). I built a computer to take advantage of the Linux realtime kernels and haven't looked back but I understand that this would mean a year's worth of work for you transferring to Pd, LOL. Is Max available for Linux, I don't know...?

My GF's dad is one of those old school "knows everything about computers from the ground up" sorta cats and is an engineer at EMC, no less. I asked him about SSDs recently and he warned me that they are not the end-all-be-all. The transistors that store information wear out after 9,000 or so read/writes (forgot which is their weakness, write makes more sense!) He suggested that their appropriate usage is to boot your OS (duh), to boot applications, but not to store data and ESPECIALLY not to be used as swap space (AKA virtual memory).
