Code Igniter makes use of eval to for example create the DB object dynamicly depending on the db driver setup…
so hiphop means NO GO for code igniter users…

It is really interesting idea to use c++ for web. Maybe in the future will be used only one for web developers. I don2T know what time will show us, Lets see .

From the narrow “the title of the post is the entirety of the content” view: yes. No one has any idea what HipHop means except for the Facebook developers.

But, as this post describes, it would mean reduced CPU Usage. Maybe this post could be subtitled, “Should I worry about HipHop yet?”

so your answer to

>>What does HipHop PHP mean for CodeIgniter?

is essentially

‘i have no idea’.

Then obviously you should give HipHop a try – there is nothing magic about CodeIgniter, it’s just PHP code. They’ve yet to release the source or tell us what features of PHP they failed to implement (other than eval()) so we really can’t setup an install of CodeIgniter running on HipHop to test or dig through the code looking for PHP functions that will not be supported just yet.

Ok, so lets say for arguments sake that I DO have those levels of traffic. My I/O is now optimized 100% and CPU is now the problem. I now have to worry about it.

You have not answered this question in any way. Saying ‘you will never reach the levels needed’ is a sweeping generalization that doesnt apply to everyones application.

@wefsdg No – everyone’s site aspires to reach those levels. The point is, don’t worry about that bridge until you get there – you have far more important things to worry about (input/output). PHP only consumes CPU cycles when a file is being parsed (roughly the time it takes a page to render when requested). If you really analyze your server, I’d be willing to bet the system clock requires more CPU usage than PHP does over the course of a month (unless, of course, you are running a popular website).

Why focus on saving 50% of 3% (CPU Usage) when you can focus on saving 10% of 30% (Database Queries)?

>The performance benefits gained by running HipHop on these server would be marginal at best, if even noticeable. These sites just don’t have the traffic to see measurable gains in performance by focusing on CPU usage<

But what if my site does aspire to have those levels of traffic? Are you saying codeigniter is not up to the job if it ever reaches them?
