I'm considering using the embedded perl module.

a few questions based on this in docs: "If a Perl module performs protracted operation, (for example DNS lookups, database queries, etc), then the process that is running the Perl script is completely tied up for the duration of script. Therefore embedded Perl scripts should be extremely careful to limit themselves to short, predictable operations."

my setup will have me querying postgres for every url to find the correct url on amazon's s3 which i proxy for.

i'm worried about blocking on: a) pg query b) proxy

will they block each other? how many nginx workers, realisitically, would i need to run?

I'm leaning towards doing all this in twisted python for now , but I'm open to nginx
