Any of those help Are you certain that the uuid module would in fact be too slow to handle the requests you expect in a timely manner? I would be very surprised if UUID generation accounted for a bottleneck in your application.
I would first build the application to simply use the uuid module and then if you find that this module is in fact slowing things down you should investigate a way to keep a pre-generated list of UUIDs around.

it helps some times As of Ruby 1.9, uuid generation is built-in. Use the SecureRandom.uuid function.
For example:

code :

require 'securerandom'
SecureRandom.uuid # => "96b0a57c-d9ae-453f-b56f-3b154eb10cda"

set "TARGETDIRECTORY=%~1"

@echo off
SetLocal

set "TARGETDIRECTORY=%~1"
set "OUTPUTFILE=%~2"
set "PROJDIR=%~3"

if not "%TARGETDIRECTORY%" EQU "" if not "%OUTPUTFILE%" EQU "" echo Missing argument/s.& exit/B
if not exist "%PROJDIR%Uuidgen.Exe" echo Uuidgen.exe not found or missing argument.& exit/B

echo Starting Dependency check...

I hope this helps .
Product-, Package-, Upgrade Code: You can use WiX's auto-GUIDs for components (for most components). Using auto-GUIDs significantly reduces WiX source complexity. Is it safe?
