After all, these are parameters that some user is supposed to configure depending on the resources available in their environment, isn't it? If the problem is to allocate the "defaults" for those memory parameters, etc, I believe it's best, like everyone else has already mentioned, we either keep separate start-up scripts for each profile or parameterize Xms, Xmx values, etc configured with the MB start-up script and assign them depending on the used profile (This is possible only if we configure some default values upon the aforesaid attributes and want to increase/drop with a known factor or something, I believe). However, the latter doesn't seem to be too much "re-usable" as it binds to the startup script of a particular product though. Also, with regard to Cassandra, well, there shouldn't be any different memory setting as it all should end up referring to memory parameters like Xmx, Xms, Xmn, etc configured within the JVM it's running in.
