 ====== Projects: Speedtest ======
-I'm testing out some new 5G antennas and after experimenting with a number of different ways to measure their performance I decided the most reliable and simplest way was to simple some real-life activity i.e. write a script that repeats a download and then plot the results in a graph.  That allows me to average out any interference, network effects etc.
+I'm testing out some new 5G antennas and after experimenting with a number of different ways to measure their performance I decided the most reliable and simplest way was just write a script that repeats a download every minute and then plot the results in a graph.  That allows me to average out any atmospheric interference (and more importantly average out all the other activity on my busy network).
+===== Download Speeds =====
 First, create some test files and put them on somewhere with reliable hosting (AWS for example):

 Then write some code that times the download and saves the result to a CSV.
-<code php speedtest.php>
+<code php speedtest-download.php>
 <?php
 while(true) {
         $time_start = microtime(true);
-        $url = "https://putitonyourowndomain.com/testfile10";
+        $url = "https://putitonyourowndomain.com/10mb-test-file";
         $data = file_get_contents($url);
         $time_end = microtime(true);

 Which gives results like this (datetime, seconds to download, average mb/s):

+===== Upload Speeds =====
+In order to track this we need two components - first, a form processor on the server (again, somewhere with reliable network, like AWS) that will accept a 4Mb upload file (and just bin it, we are only timing the upload).  Put this somewhere on your webspace.  You should add some validation and error handling, but this was just a quick test for me, so, meh.
+<code php acceptupload.php>
+<?php
+<?php
+if(is_array($_FILES['upload_file'])) {
+        if(!move_uploaded_file($_FILES['upload_file']['tmp_name'], "/tmp/speedtest")) {
+                echo "Error saving uploaded file";
+        } else {
+                echo "OK";
+        }
+}
+?>
+?>
+</code>
+Now write something that can test just the upload:
+<code php speedtest-upload.php>
+<?php
+$target_url = "https://www.yourdomain.co.uk/acceptupload.php";
+$file_name_with_full_path = "/tmp/4mb-test-file";
+while(true) {
+        $time_start = microtime(true);
+        $cFile = curl_file_create($file_name_with_full_path);
+        $post = array('upload_file'=>$cFile);
+        $ch = curl_init();
+        curl_setopt($ch, CURLOPT_URL,$target_url);
+        curl_setopt($ch, CURLOPT_POST,1);
+        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
+        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
+        $result=curl_exec ($ch);
+        curl_close ($ch);
+        if($result == "OK") {
+                echo date("Y-m-d H:i:s")."\t";
+                $time_end = microtime(true);
+                $download_time = $time_end - $time_start;
+                echo $download_time."\t";
+                echo (4/$download_time)."\n";
+                sleep(60);
+        } else {
+                echo "Error downloading ($result)\n";
+        }
+}
+?>
+</code>
+That will return in a format similar to the download test (datetime, seconds to download, average mb/s):
+<code>

+===== Upload and Download =====
+This final version tries to download a 10Mb from my server, then tries to upload a 4Mb file to the ''acceptfile.php'' file (written above) hosted on my web server.  Then it waits a minute and tries it again in a loop.
+<code php speedtest.php>
+<?php
+$download_url = "https://www.yourdomain.co.uk/10mb-test-file";
+$download_size_mb = 10;
+$upload_url = "https://www.yourdomain.co.uk/acceptupload.php";
+$upload_size_mb = 4;
+$file_to_upload = "/tmp/4mb-test-file";
+while(true) {
+        $time_start = microtime(true);
+        $data = file_get_contents($download_url);
+        $time_end = microtime(true);
+        $download_time = $time_end - $time_start;
+        echo date("Y-m-d H:i:s")."\t";
+        echo "DOWN\t$download_size_mb\t";
+        echo $download_time."\t";
+        echo ($download_size_mb/$download_time)."\n";
+        $time_start = microtime(true);
+        $cFile = curl_file_create($file_to_upload);
+        $post = array('upload_file'=>$cFile);
+        $ch = curl_init();
+        curl_setopt($ch, CURLOPT_URL,$upload_url);
+        curl_setopt($ch, CURLOPT_POST,1);
+        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
+        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
+        $result=curl_exec ($ch);
+        curl_close ($ch);
+        echo date("Y-m-d H:i:s")."\t";
+        echo "UP\t$upload_size_mb\t";
+        if($result == "OK") {
+                $time_end = microtime(true);
+                $upload_time = $time_end - $time_start;
+                echo $upload_time."\t";
+                echo (4/$upload_time)."\n";
+        } else {
+                echo "Error downloading ($result)\n";
+        }
+        sleep(60);
+}
+?>
