[SR-Users] How are SIP messages divided amongst TCP workers?

As with UDP workers, the kernel divides incoming TCP in a semi-random
way at a trough of TCP workers all calling accept(). So, the
distribution is indeed at the connection level rather than the message
level, and so long as the connection persists, messages go to the same
In theory, at sufficiently large values of N, this shouldn't be a
problem since an approximately equal number of TCP connections will be
allocated to each worker. Or are your expensive crypto workloads
distributed in a very lopsided way that doesn't touch all TCP clients
approximately equally in the grand scheme of things?
If you're really concerned about it, though:

This sounds like a reasonable solution.
