java - Why Hazelcast is fast? -

-

I have had many years of experience working with a database related to the database, but there was a question that I always had Asked. How Java-based hazelcast (in-memory) can be faster than any other non-Java based database? For example, Memory Raidis and Memkach are not based on Java.

I've heard many negative things about Java and its JVM, which slows the code 10-1000 times compared to the non-VM environment. Does it mean that everything has changed within time? I know that this is a lot better a few years back, but still due to its clear view of working on every platform, performance has decreased. So how can Java code be faster than non-virtual machine code or same speed ?

  • Search for JVM and how it "slows down the code 10-1000 times" "FUD description is FUD.
  • "DB Speed" is not just a platform, it has implementation and features.
  • The Heselcast website contains information related to implementation, GC, architecture, etc.

Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
