I’ve got an app which users can edit the ERB templates for emails, the  
changes aren’t taking effect till the app restarts though because

config.action\_view.cache\_template\_loading = true

I’ve seen various comments that suggest it has to be true when in  
Production for thread safety - is Rails actually running in a threaded  
manner yet? Surely this is a none issue at the moment?

Is anyone else running production apps with this set to false?

Thanks

PS: yeh - I know liquid would be a better option, its on the list for  
the future

Do you understand the performance hit you’ll get once you do that?

No - not really. How significant would it be?

I know this has only become a problem since the app got upgraded to  
2.2 - prior to that we must not have been caching the templates  
anyway.
