Measure download speed using incremental file sizes.

Args:
    size_limit: Maximum file size to test (default: 128MB)
    sustain_time: Duration in seconds for each test (1-8, default: 8)

Returns:
    Dictionary with download speed results

Measure upload speed using incremental file sizes.

Args:
    url_upload: URL to upload data to
    size_limit: Maximum file size to test (default: 128MB)
    sustain_time: Duration in seconds for each test (1-8, default: 8)

Returns:
    Dictionary with upload speed results

Takes a number of samples and reports the lowest
value for the most accurate representation of network latency.

Args:
    url (str): The URL to measure latency to
    samples (int): Number of samples to take (default: 10)

Returns:
    Dictionary with latency result (minimum of all samples)

Get server information for any URL without performing speed tests.

Args:
    url_download: URL to download data from
    url_upload: URL to upload data to
    url_latency: URL to measure latency to

Returns:
    Dictionary with servers information including POP location, CDN info, etc.

Run a complete speed test returning all metrics in a single call.

This test uses the smart incremental approach inspired by SpeedOf.Me:
- First measures download speed with gradually increasing file sizes
- Then measures upload speed with gradually increasing data sizes
- Measures latency and jitter
- Returns comprehensive results with real-time data

Args:
    max_size: Maximum file size to test (default: 128MB)
    url_upload: URL for upload testing
    url_latency: URL for latency testing
    sustain_time: Duration in seconds for each test (1-8, default: 8)

Returns:
    Complete test results including download, upload, latency and jitter metrics
