A synopsis of blog posts, videos, talks, presentations on topics like Performance tuning, JVM, GC in Java, Mechanical Sympathy, et al by experts from the industry.
I'll be covering three reviews of talks by Attila Szegedi (1 talk) and Ben Evans (2 talks). They speak on the subject of Java Performance and the GC. The first talk by Attila covers a lot of his experience as an Engineer at Twitter - so its lots of information out of live experience in the field on production systems. Making use of thin objects instead of fat ones is one of the buzzwords in his talk.
Ben in his two talks covers Performance, JVM and GC in great depth. He points out about people's misconception about Performance, the JVM and GC, things that people don't have certain run-time flags enabled in production. How the underlying machinery works, why it works the way it works?How efficient the machinery is and what best to do and not to do to get good throughput out of it?
Recently, I was asked to participate in creating another Java application at my company.
It was to be our team's third major Java application since 2002.
We felt we had plenty of wisdom from our previous two Java applications to apply to our third one.
One of our first steps was to form an application architecture sub-team.
This sub-team's purpose was to provide the development team with a solid...
My company uses a large number of software applications to support all aspects of its business.
These software applications are either "bought" or "built".
The portions of the company that cannot be supported by purchased software are
supported by custom developed, in-house, applications.
A variety of technologies are used to create and build these custom applications.
The Java framework has been...
A while ago, I was asked to evaluate another Java application that was being used at my company.
It was a point-of-sale app, developed entirely "in-house" by one of our overseas affiliates.
I wondered what their MVC model would look like.
How different would their Java app be from the ones I have worked on?
I started my evaluation by learning all I could about the architecture and design of this...
Just recently I was engaged to assist with an application that wasn’t behaving. The application, running in a 1.7.0_45 JVM, relied heavily on a 3rd party SAAS framework. That vendor provided my client with a list of 26 different JVM flags that should be set. When faced with this long list of flags I couldn’t resist asking why all the flags and why these flags. After all there are more than 700 product flags defined in the JVM and to be honest, I’ve only a vague idea of the effect may have on a runtime.
