For a decent subset of the procedures I've worked on, yes, I am, from experience. I've had app performance killed by excessive string concatenation before, so my inclination to repeat identical jobs at runtime which I know from experience cause performance issues is limited. Precompile. I should stress in this though, I'm not a complete 'it must be a compiled sproc stored in the DBMS' guy; I have worked with systems before which effectively provided their own stored procedure implementation within the application source code because the underlying DMBS didn't support anything else; it's not ideal for a number of reasons but it does work, is an order of magnitude superior to ad-hoc SQL scattered throughout the app, still permits some of the benefits of genuine sprocs but also still provides the dev with proper control over what they're doing.
