You can use a local fixture for the client, this way other tests could use the same.

Also it looks like a good idea to use parameterized test so each URL is tested individually and we can see each one as a result in the tests

@pytest.fixture(scope="function")
def api_client(ansible_config):
    config = ansible_config("admin")
    api_client = get_client(
        config=config,
        request_token=False,
        require_auth=False
    )
    return api_client


@pytest.mark.deployment_community
@pytest.mark.parametrize("url,baseline", URLS.items())
def test_api_performance(api_client, url, baseline):
    
    threshold = 0.25
    results = []

    start_time = time.time()
    resp = api_client('http://localhost:5001' + url, method='GET')
    elapsed_time = time.time() - start_time
    
    difference = (elapsed_time - baseline) / baseline
    assert difference < threshold

Maybe this object could get more nesting data, so we can play with different methods.

URLS = {
    '/api/_ui/v1/settings/': {
         'baseline': 0.5,
         'method': 'GET'
    },
    '/api/other_url': {
        'baseline': 0.7,
        'method': 'POST',
        'payload': {...}
    }
}
