Python’s Weak Performance Matters

Re:Python’s Weak Performance Matters by imtringued on Wednesday February 07, 2018 @07:52AM (#16324054)

The JVM is fast enough for me but for some reason any JVM project requires hundreds of megabytes of RAM even for the simplest things.

cpp webserver + sqlite database + cygwin overhead? 9MB RAM lua worker + websocket client? 4MB RAM JVM server + static html page + websocket relay + kurento api? 500MB RAM

With the exception of the cpp webserver none of these tasks are CPU or memory intensive yet the JVM is still off by orders of magnitude.

It's ok if it's the only application running on a server with multiple users but there is just a single user and that's me.

Have you tried specifying a smaller maximum heap size? The biggest memory issue IMHO, is that Java and the JVM do not specialise any "generic" code and so there can be a lot of unnecessary boxing going on.
