PHP compile: performance impact??

Hi,

I was wondering, when compiling PHP with extra options such as OpenSSL or CurlSSL or GD or FTP or TTF, or anything for that matter...

Would this have any performance impact at all on PHP itself such as execution time, or any other performance measure? Or would it simply add those options in, run in the background, and only come into play when the specific functions are requested by a script, in other words no performance impact?

I'm trying to debate if compiling certain options would affect execution time for scripts not requiring these newly compiled options. I hope all of you know what I mean! Thanks

 

In other words, yes, there is a performance impact, even if a certain script doesn't use the extension in question?

For example, would my php run faster if I loaded the extension using php.ini, instead of statically compiling it from source? Because I'd like to enable extensions that don't get used much, but wondering if these not-so-used extensions should be compiled or not?

If I don't compile, I would come to think that the PHP executable is smaller (and loads faster) containing the core structure. If the added extensions in php.ini are not loaded unless the script needs them, would this not be an advantage? Sometimes there are extensions that are needed that aren't enabled, but its only for a very small feature on a script for a small site, and is not essentially worthy of a recompile.
