My best guess is that the java one is slow due to ebean (I've always seen huge performance improvements from switching to raw jdbc). The scala one I have no clue.

More likely because the version uses only as many threads as the cpu has cores. Whereas the servlet version for example has 128 thanks to the default resin configuration.

That would definitely be an issue as well. Although, this is easily configurable within the application.conf file if I remember correctly.
