@ -10,9 +10,16 @@ This is a very lightweight Speedtest implemented in Javascript, using XMLHttpReq
## Compatibility
Only modern browsers are supported (IE11, latest Edge, latest Chrome, latest Firefox, latest Safari)
## Features
* Download
* Upload
* Ping
* Jitter
* IP Address
* Telemetry (optional)
## Requirements
- A reasonably fast web server. PHP is optional but recommended (see doc.md for details)
- Some way to generate garbage data (PHP script included, see doc.md for other solutions)
- A reasonably fast web server with PHP (see doc.md for details and use without PHP)
- Your server must accept large POST requests (up to 20 Megabytes), otherwise the upload test will fail
- It's also better if your server does not use compression, but it's not mandatory

# HTML5 Speedtest
> by Federico Dossena

@ -35,14 +35,16 @@ To install the test on your server, upload the following files:
* `garbage.php`
* `getIP.php`
* `empty.php`
* one of the examples
You may also want to upload one of the examples to test it.
Later we'll see how to use the test without PHP.
Later we'll see how to use the test without PHP, and how to configure the telemetry if you want to use it.
__Important:__ keep all the files together; all paths are relative to the js file
## Usage
You can modify one of the examples or start from scratch. If you are just editing one of the example, skip to the "test parameters" section.
To run the test, you need to do 3 things:
* Create the worker
@ -246,15 +248,49 @@ You need to start the test with your replacements like this:
```js
w.postMessage('start {"url_dl": "newGarbageURL", "url_ul": "newEmptyURL", "url_ping": "newEmptyURL", "url_getIp": "newIpURL"}')
```
## Telemetry
Telemetry currently requires PHP and MySQL.
To set up the telemetry, we need to do 4 things:
* copy `telemetry.php`
* edit `telemetry.php` to add your database access credentials
* create the database
* enable telemetry
### Creating the database
At the moment, only MySQL is supported.
Log into your database using phpMyAdmin or a similar software and import `telemetry.sql` into an empty database.
If you see a table called `speedtest_users`, empty, you did it right.
### Configuring `telemetry.php`
Open telemetry.php with notepad or a similar text editor, and insert your database access credentials
```
$MySql_username="USERNAME"; //your database username
$MySql_password="PASSWORD"; //your database password
$MySql_hostname="DB_HOSTNAME"; //database address, usually localhost\
$MySql_databasename="DB_NAME"; //the name of the database where you loaded telemetry.sql
```
### Enabling telemetry
Edit your test page; where you start the worker, you need to specify the `telemetry_level`.
There are 3 levels:
* `none`: telemetry is disabled (default)
* `basic`: telemetry collects IP, User Agent, Preferred language, Test results
* `full`: same as above, but also collects a log (10-150 Kb each, not recommended)
Example:
```
w.postMessage('start {"telemetry_level":"basic"}')
```
Also, see example8_telemetry.html
### See the results
At the moment there is no front-end to see the telemetry data; you can connect to the database and see the collected results in the `speedtest_users` table.
## Known bugs and limitations
* The ping/jitter test is measured by seeing how long it takes for an empty XHR to complete. It is not an acutal ICMP ping
* __Chrome:__ high CPU usage from XHR requests with very fast connections (like gigabit).
For this reason, the test may report inaccurate results if your CPU is too slow. (Does not affect most computers)
* __IE11:__ the upload test is not precise on very fast connections
* __IE11, Edge:__ the upload test is not precise on very fast connections
* __IE11:__ the upload test may not work over HTTPS
* __Safari:__ works, but needs more testing and tweaking for very fast connections
* __Firefox:__ on some Linux systems with hardware acceleration turned off, the page rendering makes the browser lag, reducing the accuracy of the ping/jitter test
