Query regarding performance-differences, in using a "servlet" VS "PHP module"
 

Hi all.

I was just doing some rudimentary research on what would be the best solution to implement server-side operations of our webapp.
The "servlet" and "PHP" seem two widely used solutions.


However, there is one important thing that struck me.

Looking at http://www.tutorialspoint.com/servle...life-cycle.htm, it states that every new client-request to a servlet, spawns a new thread.
On the other hand, looking at http://php.net/manual/en/internals2.....lifecycle.php, it states that the Apache module MIGHT map different requests to a single process (with the CGI model DEFINITELY using the one-process-per-request implementation).

Looking at the above, it seems that using Apache Tomcat to host a servlet, is better than running a PHP module in Apache (as far as resource-requirements are concerned at the server).

Is my understanding correct?



I will be grateful to any clearances on my doubts :)

For highly frequented websites it saves you hardware costs if you use servlet technology. If you run a website with only a couple thousand users you are probably better off with a php or ruby solution (as development costs are lower).
Of course I am strongly generalizing. It's a rule of thumb only.
