# what is high throughput?

**High throughput** refers to a system’s ability to **process a large volume of work in a given amount of time**, usually measured as **requests, transactions, or data per second**.

In short:

> ## High throughput = How much work the system can handle per unit time

## Simple Example

- System processes **10,000 requests per second**
- That system has **high throughput**, even if each request takes some time

## Formal Definition

> **Throughput is the rate at which a system successfully completes operations over time.**

## Common Throughput Metrics

| Context | Metric |
| --- | --- |
| Web APIs | Requests per second (RPS) |
| Databases | Transactions per second (TPS) |
| Streaming | Messages per second |
| Networks | Mbps / Gbps |
| File systems | IOPS |

## High Throughput vs Low Latency (Very Important)

| Metric | High Throughput | Low Latency |
| --- | --- | --- |
| Focus | Volume of work | Speed of response |
| Unit | req/sec, TPS | ms |
| Can exist together | Sometimes | Sometimes |
| One does NOT guarantee the other | True | True |

### Example

- A system handles **50,000 req/sec**
- Each request takes **400 ms**

   - **High throughput,** [**high latency**](https://www.mindstick.com/interview/34441/what-is-latency-in-software)

## Real-World Analogy

- **Throughput** → Number of cars passing a toll per hour
- **Latency** → Time taken for one car to pass the toll

## What Makes a System High Throughput?

### 1. Parallelism

- Multiple threads
- Multiple cores
- Distributed processing

### 2. Asynchronous / Non-blocking I/O

- Async APIs
- Event-driven systems

### 3. Batch Processing

- Process data in chunks
- Reduces overhead

### 4. Efficient Resource Usage

- Connection pooling
- Caching
- Reduced locking

## High Throughput in Real Systems

## Examples

- Payment gateways
- Message queues (Kafka, RabbitMQ)
- Logging systems
- Streaming platforms
- Bulk email senders (relevant to your background)

## High Throughput vs Scalability

| Concept | Meaning |
| --- | --- |
| High Throughput | Handles many requests |
| Scalability | Ability to increase throughput by adding resources |

A system can:

- Have high throughput but not scale well
- Scale well but still have low throughput per node

## When Throughput Matters More Than Latency

- Background jobs
- Batch processing
- Analytics pipelines
- ETL jobs
- Email sending systems

## Interview One-Liner

> **High throughput means a system can process a large number of requests or operations per second.**

## Quick Comparison Table

| System | Latency | Throughput |
| --- | --- | --- |
| Chat app | Low | Medium |
| Payment system | Low | High |
| Logging pipeline | High | Very high |
| Bulk email sender | High | Very high |
