i have just upgrade to ci 3.0 for few days. (just copy old code to new ci 3.0 folder then re-config)
When running with same config, i found out ci 3.0 run slower than 2.2 versions
In ver 2.2:
code execute < 100ms
ver 3.0:
code execute > 1100ms
All external files in 2 versions return same loading time (few percent difference)
But time to execute code in ver 3.0 is ten times slower than 2.2.
It's not worth upgrading, if website need 1 second more to execute
Can anybody help me, please?

Test again
Just download 2 versions of codeigniter
Install then run welcome page.
Give same result.

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.

I noticed you are running the Dev version, try using 3.0 version.
The low value on my site is no doubt helped because the server uses a SSD.

Yes, i saw it.
But in system/libraries/Session/drivers/Session_database_driver.php line 94
CI will auto aborting if "pconnect" config set TRUE
Disable that lines and set pconnect TRUE will increase performance to ~30 milisecond loading.
(Why did they let us config while treat it like an error? LOL)
By the way, with CI 2.2.0 i can set pconnect TRUE, FALSE and whatever it is, page loading time always < 10 milisecond (my favorite framework, fast like hell  )

Yeah, well ... if you want to set pconnect to TRUE, don't use database sessions. It's all made that way for a reason.

I had problems with performances as well on my app built with CI3 and at the end i found that all the issues were related to database sessions, in fact switching from db to file session everything is now super fast.
Note: the problem was noticeable only online when hundreds of users were connected and using the software at the same time.
