Incredibly Slow CodeIgniter Application

[eluser]Diamons[/eluser]
I bought a script based off of CodeIgniter (http://bit.ly/ll01Kr). The execution time for the homepage and some other pages is 7ms+. Sometimes, I even get 15ms. This is all using the CodeIgniter profiler.

If i delete the entire view file or template file, I get speeds of < 1ms. So I believe the view files are causing a delay. Can anyone help me out with this?

How is 15 milliseconds slow, again?

We can't help without seeing the code causing the issue. Please use a service like Pastebin if you want to show the code here, since the forum both limits the amount you can post, and will mess with some source code.

Fif... Fif... Fi... I can't even type "fifteen" in fifteen milliseconds...

[eluser]Diamons[/eluser]
Whoops! 15 seconds, not milliseconds.

is the code for the homepage

I suggest mentally breaking your app up into pieces, with the [url="http://ellislab.com/codeigniter/user-guide/general/profiling.html"]profiler[/url], and add benchmarks into your application flow. Use a bit of common sense, and move the benchmarks around in your app to see if you can find the bottleneck(s).

I can't profile it for you, you'll need to do that yourself.

Solved, thank you! This was my first time having any such issue so I had no idea where to begin...but for others having the same issue, I did the following.

I used this code: http://www.3cc.org/blog/2010/09/benchmar...microtime/

I basically did what @TheFuzzyOne recommended and just broke down the site until I found the lines causing the delay. It turns out the script had a poorly written currency converter that would make a request to Google every time.

[eluser]TheFuzzy0ne[/eluser]
Glad you got it sorted.

But for the record, the profiler's benchmarking facility works in (almost) exactly the same way.

Are you talking about XDebug, or the built in CI one? I used the built in CI one and it just gave me one large output but it didn't explain what was going on.
