Slow Upload in PHP joomla controler - php

Question

here is the code that i use to upload files and unzip them in a directory.
But the problem is that it seems to be very slow on files greater than 5MB.
I think it doesnt have to do with the network because it is in localhost computer.
Do I need to edit any parameter in php.ini file or apache or any other workarround?
$target_path = "../somepath/";
$target_path .= JRequest::getVar('uploadedDirectory')."/";
$target_Main_path= JRequest::getVar('uploadedDirectory')."/";
$folderName = $_FILES['uploadedfile']['name'];
$target_path = $target_path . basename($folderName);
//upload file
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path."/")) {
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
$zip = new ZipArchive;
$res = $zip->open($target_path);
$target_path = str_replace(".zip", "", $target_path);
echo $target_path;
if ($res === TRUE) {
$zip->extractTo($target_path."/");
$zip->close();
echo "ok";
} else {
echo "failed";
}

When handling file uploads ther are a lot of factors to consider. These include PHP settings:
max_input_time
max_execution_time
upload_max_filesize
post_max_size
Execution time can affect the upload if for example, you have a slow upload speed resulting in a timeout.
File size can cause problems if the upload is larger than the upload_max_filesize like wise if your file size + the rest of the post data exceeds post_max_size.
Zip uses a lot of memory in the archive/extraction processes and could easily exceed the memory allocated to PHP -so that would be worth checking as well.
I would start with this page and note some of the comments.
