Hi Ron, just because I think this might be interesting to people dealing with really high rates: The maximum size is typically limited by the size of mmap'able memory that you can allocate; that depends on the circular buffer factory used: For the posix shared memory thing, I don't think anything is stopping you from using "memory space size" order amounts of buffer. For anonymous file-backed mmap'ed buffers, I'd expect that we haven't addressed the possibility of using more than 32 bit addresses, so somewhere around 2 GB you'd find your upper limit.
