What is TPS (Transactions Per Second)?

Last reviewed July 22, 20261 min readReviewed by BroadNet engineering

Quick answer

TPS (transactions per second) — also called MPS or send rate — is the throughput ceiling of a messaging bind or account: how many SMS submit_sm PDUs the SMSC accepts per second before it returns throttling errors. A2P binds are provisioned at a contracted TPS; exceeding it triggers ESME_RTHROTTLED responses. TPS, not raw volume, determines how fast a campaign or OTP burst clears. See /answers/what-is-throughput-sla, /answers/what-is-cps, and /tools/smpp-error-codes.
