Hi

php -w will return the stripped sourcecode (whitespace and comment).
It will not run the script.

If you reduce your filesize by removing comments, you will get:
1) a slightly faster execution (don't expect too much).
2) A headache if you want to modify the code and the usefull comments are
stripped out.

My advise: Don't do it.

If your application is slow, find out why. I am quite sure it is NOT the
commentlines that makes the application slow.

Just do some simple profiling, using microtime() to store the time for each
thing that happens in your script.
In my experience, 9 out of 10 times the reason for slow webapps is a poorly
designed database, or poorly designed query logic.
for example: running 40 seperate queries to build 1 page.
