I have written a script when clicked it creates a zip archive of files from the server and start downloading. Till this point everything is fine but what annoys is that it freezes the browser whether it be Chrome, Mozilla or IE. I assume this is due to overheard of creating a zip file and then downloading that altogether. This is on a dedicated server with 32 Gigs of RAM so I wonder is this really an issue with server. What is the alternate way of downloading the file smartly. Here is the link for demo.

Works fine for me. I waited until 15Mb downloaded then cancelled - I don't need it. Perhaps if you want help, you should at least warn people about the size of the download. Also a notification to let the user know the size of the download on the site would also be useful.

"The download will start..." is confusing - I assumed that you'd wangled it to automatically download a file to my PC somehow. Warning! Warning!

So where's your problem?

Also, while trying your download link, I got this:

The header is different from a valid one, because there is no reference to the file to download and that's correct, but note that the query is revealed because it occurs even if the captcha is not submitted, and since the $id is not set, it generates that output. In other words, make sure to stop the execution before running that query.
