[RESOLVED] performance issues with huge includes

[itaym02]

Hi ALL

I need to verify a point.
The way code is organized in my company system is we include everything (all functions and classes files) in each request which is a several MB of code (life as programmer are a bit easier).
We use APC so all the code is being included from memory (We use full path to avoid overhead here).
I have a feeling that although we use APC, the Apache instance gets to be too bloated then how it would have been if we would only include the files we need to include in each request,
Say, using __autoload.

Does someone knows if this is the case, or not?

Thanks
Itay

It would certainly take away a few tens of milliseconds from page load but not enough to make you notice any difference. If you don't really care about optimum performance, this shouldn't matter to you.

I am not worried about the time, just the memory consumption. I would have tested it, but it is in production so I try to find out as much data as I can before I play in production.

Work out what the immediate dependencies are between all the different files, and have each file start by using require_once() to load only those immediate dependencies. Trust those dependencies to load their dependencies. Then on any given request only those files that actually need to be loaded get loaded. It also provides some self-documenting code about what a given file depends on.

You can also strategically use [man]memory_get_usage[/man] and [man]memory_get_peak_usage[/man]
