Answer 1

This is the content of the php script and i run it 10500 via this command for i in {1..10500..1}; do php upload.php; done
<?php
$conn = new Mongo("127.0.0.1:27017"); // Connect
$db = $conn->uniform_server; // Select DB
$db->authenticate("user","passwd"); // Authenticate to MongoDB
$grid = $db->getGridFS(); // Initialize GridFS
$tab_pj = array("document0.pdf",
"document1.tif",
"document2.doc",
"document3.png",
"document4.JPG",
"document5.xls",
"document6.rar",
"document7.ppt",
"document8.rtf"
);
$pj_id = rand(0,8);
$name = $tab_pj[0]; // Get Uploaded file name
$id = $grid->storeFile($name); // Store uploaded file to GridFS
$conn->close(); // Close connection
exit(0);
?>
