…sses SIPp is single-threaded, so one uac tops out at about one core (350 calls/s over TCP) however big the load generator is. load.instances: N starts N uac processes, each with 1/N of the rate and the open calls, its own port, Call-ID prefix and share of uac.users. The sampler names each process, the step check judges the busiest one, and the analysis sums them all. infra.loadgen.count is left as a design note.

…n a row break a rule A step that breaks p99LatencyMs or failedCallsPct while the next one passes is a spike: the ramp goes on, the step is flagged spike in the report and on the live page, and the limit stays the last step before a confirmed break. Default 2; 1 keeps the old behavior. A break on the last step and an unmeasurable (saturated load generator) step still end the ramp at once.

…IPp processes load.instances stays the total and is spread round robin over the droplets; each worker's SIPp files are pulled back to the first droplet over SSH, with their pids renamed so two machines never collide.

Three steps on top of #26, each tagged and run on DigitalOcean:
load.instances: a benchmark's uac split over several SIPp processes (rc.2)thresholds.confirmSteps: a capacity ramp ends only after N steps in a row break a rule (rc.3)infra.loadgen.count: more load generator droplets, instances spread round robin, their SIPp files copied back to the first (rc.4)Smoke run of the last one is in progress; merging after it passes.
