# Throughput & connections

> HTTP and SMPP throughput limits and concurrent connection rules.

Throughput and connection limits control how many messages and sessions your account can handle per second.

## Definitions

| Term                           | Meaning                                                                               |
| ------------------------------ | ------------------------------------------------------------------------------------- |
| **Throughput (TPS)**           | Maximum number of transactions (SMS submissions and DLRs combined) allowed per second |
| **Max connections**            | Maximum number of simultaneous HTTP or SMPP connections to the Messaging Platform     |
| **Persistent HTTP connection** | Counts as **one** connection while kept open — multiple requests may share it         |

## Default account settings

When a new Multicountry SMS account is created, the platform applies these defaults:

| Setting              | Default                                                            |
| -------------------- | ------------------------------------------------------------------ |
| **Throughput (TPS)** | **25** transactions per second (SMS submissions and DLRs combined) |
| **Max connections**  | **No limit**                                                       |

During onboarding, the Beem sales team may adjust TPS and connection limits based on your use case and requirements. Confirm your account's current limits with your Beem account manager or [support@beem.africa](mailto:support@beem.africa) before load testing.

## HTTP persistent connections

The platform supports HTTP/1.0 and HTTP/1.1 with persistent connections:

* Do **not** send `Connection: close`
* Do **not** close the socket after each message
* Read each response before submitting the next request

See [Sending messages](/guides/multicountry-sms/sending-messages#persistent-http-connections).

## SMPP

SMPP accounts use separate bind and TPS settings. See [SMPP integration](/guides/multicountry-sms/smpp) for bind types, `DEFAULT-TPS`, and `MAX-WINDOW-SIZE`.
