I'm trying to say that each message can take some time to arrive (a delay), and that each such delay can have any value. So, which one of the following is the most appropriate?
There is no bound on message delay.
There is no bound on message delays.
There is no bound on messages delays.
Also, there is a number of processes, running at different speeds, and the speed difference is unbound. So a similar question would be what's the best combination of words for the following sentence?
There is no bound on relative process/processes speed/speeds?
