What does throughput mean in software engineering?

Throughput is the amount of work, data, or requests your system can process in a given time period, usually measured per second. For example, a web server with throughput of 1000 requests per second can handle 1000 requests every second.

How do you use throughput in a sentence at work?

You typically use it when discussing system performance or capacity: We need to improve throughput to handle peak traffic, or The database throughput is 5000 queries per second.

Is throughput formal or informal?

Throughput is neutral in formality. It is used in both casual team conversations and formal technical documentation. It is appropriate in meetings, code reviews, and written reports.

How does throughput differ from latency?

Latency measures how long a single request takes to complete, while throughput measures how many requests the system processes per unit time. You can have low latency but low throughput, or high throughput but high latency.

What is a real-world example of throughput?

A checkout page that processes 500 orders per minute has a throughput of about 8.3 orders per second. A message queue that handles 100,000 messages per second has very high throughput.

Say it like this

✓We need to double our throughput to meet the SLA.

✓High throughput is essential for this API endpoint.

✓The system is running at maximum throughput.

Real examples

in a standup

"Yesterday we optimized the message queue, and our throughput increased by 40 percent."

in a code review

"Using batch processing here will significantly improve throughput without sacrificing accuracy."

in a team meeting

"Our current database can handle 10,000 requests per second, but we need 50,000 to meet demand, so throughput is our main blocker."

Don't say this

Handle with care. Often confused with latency or speed. Throughput measures quantity of data processed per unit time, not how fast individual requests complete.

✕This server has high throughput, so requests will be very fast.

✓This server has high throughput, meaning it can process many requests per second, but each request might still take time.— Throughput is about volume, not speed. High throughput does not guarantee low latency.

✕We improved the throughput by reducing latency.

✓We improved the throughput by optimizing the database query and adding caching.— Latency and throughput are different metrics. You optimize them with different techniques.

✕The throughput of this function is slow.

✓The throughput of this function is low, or this function is slow to execute.— Throughput is measured in quantity (high or low), not in speed (fast or slow).
