PDF and Ruby on Rails

Hi,    I am sticking in one problem. Please help me out. The problem is like:

   What problems can arise when users hits the get_pdf action?    If there are problems, how can it be solved?

class PdfController < ApplicationController   def get_pdf     send_data Pdf.create(params[:contents])   end end

class Pdf   def self.create(contents)     make_pdf(contents) # takes 30 seconds to run   end end
