Hi,

I tried the bundle\_fu plugin,

and as of moving to production, I noticed, that my views render in  
70ms without bundle\_fu, and about 1800ms with it!

It’s not always 1800 but most of the time.

Is this ok? Shouldn’t I turn some caching in bundle\_fu to on?

Use Rails in-built caching instead. If you want to use bundle\_fu to  
obfuscate your scripts, then you need to note that it will take a long  
time the first time the server is run for doing the caching.  
Subsequent requests will be faster.
