Where is the best place in the stack network to ask questions about or recommendations for 3rd party resources, tools, etc...? The question I'd like to ask is:
I'm looking for a way to understand/test my .PHP code to see which method of doing something is more efficient and/or requires fewer server resources.
Does anyone know of a website, system, or method for testing different versions of code to see which requires the least amount of server resources and/or time?
As was pointed out in the comments, Software Recommendations is the place to ask for tool recommendations.
However!!!
The site has very strict quality guidelines. They have to prevent spammers from filling up the site, or people just suggesting their favorite tool. So, you must have very specific requirements in your question.
Their guidelines are here and are also linked from their Help Center.
There is one other aspect to your question here. If you aren't interested in tools, but in a constructive criticism of your code - then Code Review is the place to go. That is where you can post your code and ask others to look at it.
The difference between Code Review and Stack Overflow is that Code Review is for code that already works, but that you want to improve.
