What is so slow here? The render takes up 8% and the queries take up  
1%. That leaves 91% unaccounted for.

Completed in 0.06477 (15 reqs/sec) | Rendering: 0.00574 (8%) | DB:  
0.00087 (1%) | 200 OK [[http://localhost/](http://localhost/)]

Any help would be appreciated.

The other 91% is the time it takes to render that to the log file. 😉

Actually… that’s bizarre.

That’s going to be all the code that isn’t a rendering or a database  
access. You’re the one with the code so you should know 🙂
