I'm a php developer, but recently had to write the same application twice, once in php and once in java, for a class I'm taking at school. For curiosity I did a benchmark on the two and found that the java version was 2 to 20 times slower than the php version if the database is accessed, and 1 to 10 times slower without DB access. I see two immediate possibilites:
- I suck at java.
- I can finally tell people to quit whining about php.
I posted my servlet code here. I don't want any nit-picky whining or minor improvements, but can someone see a horrible glaring performance issue in there? Or can anybody explain why Java feels like it has to suck?
I've always heard people say that java is faster and more scalable than php, especially my teacher, he is convinced of it, but the more requests that are made, the slower java gets. php doesn't seem to be affected by increased loads but remains constant.
