To measure a Selenium navigation, start a monotonic timer immediately before driver.get(url) and stop it as soon as the call returns. That gives you the duration of the WebDriver navigation call under the browser’s configured page-load strategy—not a universal measure of when every part of a modern web app is ready. For browser-reported document milestones, use the Navigation Timing API; for a usable app workflow, time an explicit condition such as a target element becoming visible.
Choose what “page load time” means
These measurements answer different questions, so report the method and event rather than publishing an unlabeled “load time.”
| Method | What it measures | Best use | Main caveat |
|---|---|---|---|
Monotonic clock around driver.get() |
Elapsed time for the WebDriver navigation call under the selected page-load strategy | A simple, repeatable navigation measurement | Includes WebDriver/browser coordination; the strategy changes when the call returns |
| Navigation Timing API | Browser timestamps for the current document navigation | Document-level milestones and intervals | Does not automatically measure later application readiness |
| Explicit wait for an app condition | Time until a chosen element or state is usable | Dynamic pages and user-workflow readiness | The condition must represent the outcome users need |
| ChromeDriver performance logs or tracing | Browser Timeline, Network, Page events, and trace data | Diagnosing contributors to a slow navigation | Must be enabled; tracing adds overhead and its buffer can fill |
| Chrome DevTools Performance recording | CPU/runtime profile | Investigating runtime bottlenecks after a slow result | A diagnostic profile, not a single page-load duration |
Measure the WebDriver navigation duration
Use a monotonic clock so that system clock adjustments do not distort the elapsed duration. This Python example reports the time spent in driver.get() in milliseconds. It assumes Selenium and a compatible browser driver are installed and configured.
from time import perf_counter
from selenium import webdriver
url = "https://example.com"
driver = webdriver.Chrome()
try:
start = perf_counter()
driver.get(url)
elapsed_ms = (perf_counter() - start) * 1000
print(f"driver.get() duration: {elapsed_ms:.1f} ms")
finally:
driver.quit()The result is the duration of the WebDriver call under the session’s page-load strategy. Selenium’s default normal strategy waits for the document load event / complete state before returning. It does not guarantee that subsequent JavaScript-driven updates in a single-page application have finished. Include the browser, test environment, URL, and page-load strategy when comparing results.

Change the page-load strategy deliberately
Selenium describes normal as waiting for the document to reach complete, eager as waiting for interactive / DOMContentLoaded, and none as not blocking on page load. Changing the strategy changes what the timer means; it is not a neutral way to make the same measurement faster. See Selenium browser options for the strategy behavior and browser-specific configuration.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.page_load_strategy = "eager" # "normal", "eager", or "none"
driver = webdriver.Chrome(options=options)Use the same strategy across runs intended for comparison and state it with the result. With eager or none, the navigation call can return before the page’s full load event, so add a separate condition if the test needs a later milestone.

Read browser navigation milestones
The Navigation Timing API exposes timestamps for the current document navigation. Read the entry after navigation and calculate the specific interval you need; do not treat it as interchangeable with wall-clock time around driver.get().
timing = driver.execute_script("""
const entry = performance.getEntriesByType('navigation')[0];
if (!entry) return null;
return {
startToDomContentLoadedMs: entry.domContentLoadedEventEnd - entry.startTime,
startToLoadEventMs: entry.loadEventEnd - entry.startTime,
responseStartToResponseEndMs: entry.responseEnd - entry.responseStart
};
""")
print(timing)startToDomContentLoadedMs is the interval from the navigation entry’s start to the end of DOMContentLoaded. startToLoadEventMs runs from that start to the end of the load event. responseStartToResponseEndMs is the response interval between those browser timestamps. Label the interval you report and consult MDN’s Navigation Timing documentation for the browser API and its timestamps.

Measure when a dynamic page is ready for a workflow
A document’s readyState is not proof that client-side rendering, data fetching, or other app work is complete. Pick an observable condition that corresponds to the user action the test is about—for example, a results panel appearing or a loading indicator disappearing—and record its time separately.
from time import perf_counter
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
start = perf_counter()
driver.get("https://example.com/search")
WebDriverWait(driver, 15).until(
EC.visibility_of_element_located((By.CSS_SELECTOR, "[data-testid='results']"))
)
workflow_ready_ms = (perf_counter() - start) * 1000
print(f"Search results visible: {workflow_ready_ms:.1f} ms")The timeout is an example test limit, not a recommended page-load threshold. Choose a limit appropriate to the test and environment. Selenium notes that navigation commands wait for a strategy-dependent readyState, while dynamic content can still cause race conditions; an explicit wait for the relevant condition is the meaningful readiness check. See Selenium waiting strategies.

Diagnose a slow result
Collect ChromeDriver performance events
ChromeDriver performance logging can collect Timeline, Network, and Page events when enabled for a new session; it is not enabled by default. Use it to investigate where time went, not as a substitute for a consistently defined navigation timer. Tracing can add overhead and its buffer can fill, so keep diagnostic tracing separate from lightweight timing runs and inspect logs for warnings or missing events.
Configuration details and limitations are documented in the ChromeDriver performance logging guide.

Record a DevTools runtime profile
After identifying a slow run, a Chrome DevTools Performance recording can help inspect CPU profiles and runtime bottlenecks. The profile provides diagnostic evidence about work in the browser; it is not itself the Selenium navigation duration. See the Chrome DevTools Performance panel documentation.
Make timing runs more useful
- Keep the page-load strategy, browser, driver, machine or remote execution environment, and test conditions consistent across comparisons.
- Separate lightweight timing runs from tracing or profiling, which can add overhead.
- Report which event or interval was timed—WebDriver call return, DOMContentLoaded, load event, or app condition—rather than calling all of them “page load.”
- Do not infer that later app activity is complete just because the document reached
complete. - No universal “good” load-time threshold follows from these browser APIs; set targets for the user outcome and environment your test represents.
Troubleshoot common measurement problems
- The timer looks much shorter than expected: Check whether the session uses
eagerornone. The navigation call may return before the load event. Report the strategy and add an explicit later milestone if needed. - The timer ends but the page is still changing: The measured event may be document readiness, not application readiness. Wait for the specific element or state needed by the workflow.
- The result varies widely between runs: Confirm that the same strategy, browser, environment, and timing endpoint are used, and avoid comparing tracing-enabled runs with lightweight runs.
- Navigation Timing returns no entry: Check that the script runs in the intended document after navigation and that a navigation entry is available; label missing data rather than substituting another interval silently.
- Performance log events are missing or warnings appear: Verify logging was enabled when creating the browser session. If tracing is active, check for buffer warnings or overflow and reduce diagnostic capture scope.
- An explicit wait times out: Confirm the selector matches the current page and that the chosen condition represents the actual ready state. A document load event alone does not guarantee a dynamic element will appear.

Frequently Asked Questions
Does Selenium measure network speed with driver.get()?
No. The elapsed call duration includes browser and WebDriver behavior under the configured strategy; it is not an isolated network-speed measurement.
