Multiplex vs Separate Gateways for Multi-Profile Hermes
Detailed trade-off analysis of running one multiplexed gateway (gateway.multiplex_profiles true) versus a separate gateway per agent profile. Covers failure domains, cron duplication, blast radius of runaway loops, log isolation, and the real meaning of isolation (process count is not a security boundary). Recommendation: multiplex unless a profile has its own channel, needs pinned runtime, separate user/limits, or must survive others’ restarts.
Why it matters
Directly useful for anyone running more than one Hermes bot. Cuts through the common “just multiplex for RAM” advice and surfaces the actual operational costs.
