One important point. The way you use output(): 
print FILE $template->output();

[download]
requires memory to hold the entire string returned from $template->output(), which can be quite big in some cases, and at the same time, slow down the process.

The output method does take a named parameter "print_to", which allows you to pass a file handler as the output file. If you specify this parameter, the method will write to that file on fly, and return undef, thus largely reduce the memory required.
