help http_load FAQ
What does http_load measure?
http_load measures how a web server handles many HTTP requests over time. It can show response behavior when several users access a page at once.
How does http_load simulate traffic?
The tool sends concurrent HTTP requests to a target URL. This creates a simple load test that can reveal slow responses or reduced performance under stress.
Is http_load the same as WebPageTest?
No. http_load is a command-line load-generation tool, while WebPageTest is a broader web-performance testing service. http_load can still be used as one component of a basic server stress check.
What can http_load reveal about a website?
It can help reveal how response times change as concurrent requests increase. The results are useful for spotting server-side limits, but they do not replace browser tests for layout or user interaction.
