> Honest question, have you ever owned a large-scale, low-latency service in both Java and PHP, and have you compared latency characteristics between both runtimes?
No, if I've worked at a shop with a large scale low latency PHP app, they aren't not bothering their ass with Java, no need. They clearly have a highly comptent dev team who know their tools.
The only time I've dealt with Java is when companies are moving away from Java because their Java app is bloated beyond hell. They have a dev team that aren't highly comptent and think switching languages will help.
If I was dealing with the two, I would most certainly expect the Java one to handle scale better. But if I'm at lower level scale I would expect the PHP one to require less resources. Once PHP starts to scale up it can be a resource hog.
The reality is the comptency level of your dev team is the most important thing.
A think you need to remember, the JVM can scale massively well but the majority of systems don't need to scale well.
