3.0 significantly slower than previous versions?

Check http://forum.codeigniter.com/thread-1579...erformance

Thank you, but still not work. 

Hi shank,

Version 3 is a big improvement and once optimized is not slow.

Yesterday I eventually made the "Calendar Class" Google Mobile Friendly but the results are still to be cached. Time to load, etc, is shown on the last line.

I am very happy with the results 

I don't know how can you make it running in ~600ms - 800ms (its faster than my base code i dowloaded on codeigniter's site) but just see the base code welcome.php(default db, default config)
   
In CI 2.2.0, Page load is faster than blink of an eye.
