There is a risk to using this module, but also a significant benefit: speed. The risks come from: - the fact that your script has been written to run one and then exit, so you may have a number of variables that aren't initialised properly - this can produce unexpected errors - ModPerl::Registry wraps your script in another sub, which may produce unexpected closures (you would see warnings about variables not remaining shared in your log) So if you move to using Registry, then you will need to check your scripts. However, using Registry means that your script is loaded and compiled once, avoiding this performance hit for subsequent requests - hence it runs faster. Have a look at this post that I wrote about gotchas under Registry, it may help you migrate: http://www.gossamer-threads.com/lists/modperl/modperl/94203#94203 Clint
