Those numbers seem very reasonable to me.

But I never serve static content with Catalyst in production. Static::Simple is
for development only.

Your benchmark is accurate but it's measuring apples and oranges. Catalyst is
not optimized for serving static content, because there's already good tools
that do that. It's optimized for development of dynamic content.

Why not measure how many requests your web server can serve for dynamic content?
