PHP ,JAVA or Ruby?
<p>I am thinking of starting a web based service .. i am an experienced JAVA developer, i was wondering if i should learn Ruby or PHP if they are better than JAVA or i can stick with JAVA and achieve better quality .
I have checked that Twitter now switched from Ruby to a JAVA server called Blender which increased their search response three times. </p>

<p>Update:</p>

<p>Will mainly my question was to know if there are any advantages for PHP or Ruby servers over Java regarding their scalability, response time .. etc and i gave Twitter as an example, i know that lots of successful services like Facebook, Yahoo, wikipedia and many others are using PHP but will that make PHP better ?
Mainly what i am planning to do requires lots of processing as it aggregates lots of information collected from the web .. so response time is a vital issue for me ..</p>

<p>i hope i made my question clearer now </p>

<p>thanks you</p>

<p>Will appreciate any help</p>
