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
