What has everyone found to be the limit to the number of interfaces you can poll per polling station? Is there a way to thread the polling process so it does more than one at a time (i.e. non-linear or parallel polling of multiple devices and interfaces)? We are polling over 500 interfaces but I found that the polling process takes a while. I am not concerned about saturating the network since it splits across multiple switches/routers and various circuits.
TIA.

Yea, I have several books that cover concurrency, even in Java. C would be my choice for multi threaded task coding, as there are lots of examples. Multithreading in interpretive languages, is an active
area of research, and is quite tricky, since scripts (interpretive languages) do not get low level access to the kernel resources directly. They access low level kernel resources through many things, such as a process table and scheduler.
Asynchronous polling would be the approach I would take with an interpretive, scripting language. But, if UDP is the protocol you choose, you could find yourself with a challenge.
However, I have not studied the code that comprises jff, so these comments are rather academic.
