Hi, I think that there are two points here,
One is passenger with standard ruby, and the other with REE. As far as Passenger goes, I would recommend it to people who start fresh (e.g. migrating from webrick). for REE - memory usage, I thought that passenger REE(GC) optimizations are not relevant to rack applications, however, I spend the last 30 minutes looking for that article I had in my mind, so maybe I'm wrong about it. Currently, when I have a mongrel process which abuse memory, monit restart it, which causes some clients to think the server has gone away (not sure why apache doesn't move it to another process) - but that happens so rarely, that its not a huge motivation to migrate. All in all, passenger simplifies a lot when it comes to managing puppetmaster processes, and its also dynamic (e.g. it wont load a lot of processes if there is no need) - so maybe it would save memory usage anyway. How do people benchmark? anyone has a good way to simulate load?
