It shouldn't be, it is much leaner than Unix. The performance issue with Java can be its interpreter unless it has a pretty smart JIT Compiler.

There have been event/message driven systems for a long time. IMS/DC (along with IMS/DB) after having been initially developed for NASA became available in 1968.

I programmed my first DC program in 1975 in COBOL using an event (transaction) driven structure. The number of concurrent programs was only limited by the number of started "Message Regions". COBOL at the time was limited by not having a dynamic storage class which was remedied in version 3 (dynam, res, rent compiler options). This was a major reason for the early popularity of CICS at the time in smaller shops. CICS emulated the dynamic memory allocation model for COBOL and was less resource intensive than IMS.

Business functionality has very rarely anything to do with the programming language used. It just about always is a function of money and ability to implement a complex system. Starting in 1976, at Swiss Bank Corporation (now UBS) you could walk into any branch around the world and just about do any banking transaction online including opening, closing accounts, depositing money as well as doing brokerage transactions. All in COBOL and IMS/DB/DC.
