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

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
