Oracle’s Java 9 Hotspot VM ships with the Garbage First (G1) GC as its default garbage collector. This GC, first introduced in Java 7, has the unique ability to efficiently and concurrently deal with very large heaps. It can also be configured to not exceed a maximum pause time. In this post we’ll take a look at how the G1 works compared to other collectors and why it can so easily outperform other state-of-the-art GCs on large heaps. Most state-of-the-art GCs classify heaps into either young generation or old generation objects. This is done mostly because studies of real-world Java applications have shown that more than 90% of objects don’t survive their first garbage collection. Older objects (objects that have survived a few collection cycles) however tend to remain alive and have a 98% chance of surviving. Java GCs split the young generation objects further into... (more)

The Key to Cache: An Intro to Varnish

We’ve published several articles on the topic of caching and its role in optimizing web performance in the past. In this article, we will focus specifically on varnish, which is an HTTP accelerator otherwise known as caching HTTP reverse proxy. What are HTTP Accelerators? HTTP accelerators use techniques such as caching, prefetching, compression, and TCP acceleration to reduce the number of requests being served by the web server. Accelerators are primarily of two types: Web client accelerators Web server accelerators Varnish is an example of a web server accelerator which serves as a reverse proxy server and is installed in front of web/application servers. It focuses on reducing the number of requests being served by the web/application server by caching the responses returned from the web server, thus allowing less bandwidth usage and reducing the server’s load. ...

Why Salesforce Admins Need No Code Process Management

No Code Process Management In, Process Builder allows the creation of fairly simple workflows such as pushing a chatter feed to an opportunity.  When Process Builder falls short, admins (and developers) spend significant time and resources coding business logic and workflow actions in an attempt to define the complex decision-making that most users require. Programming business logic and workflows eats up valuable development time, but making changes to hard-coded business logic is the real time killer because it forces the business to wait for the developers. Using no-code process management lifts business logic and process workflows out of the trap of custom code and allows business users to fine-tune the configuration or update the workflow as needed. This approach also allows admins to collaborate more closely with business analysts and subject mat... (more)

Exclusive Q&A with Jeff Haynie, Co-Founder & CEO, Appcelerator

"Companies have invested a significant amount of money in SOA – and continue to do so," says Jeff Haynie, Co-Founder & CEO of Appcelerator, in this exclusive Q&A with SYS-CON's AJAX & RIA Journal in the run-up to Appcelerator's session on October 20 at AJAX World RIA Conference & Expo in San Jose, California (October 20-22, 2008). "One of the keys to unlocking the full return on investment in SOA is the ability to build service-oriented UIs (SOUIs) – clients designed to consume services, regardless of language or platform," Haynie continues. "We believe Appcelerator's approach truly zeros in on the need for a clean separation of the application from services in an agile development model," he adds. Read the interiew in full below...

Strong User Experiences | @CloudExpo @Catchpoint #DevOps #APM #WebPerf

Delivering Strong User Experiences in This Increasingly Digital World This article was originally published as a byline for CMS Wire. Given the increasing reliance on digital systems to accomplish many everyday tasks, there’s no denying the performance — specifically, speed, and reliability — of these systems is critical to ensuring end users will have a positive experience.

PalmSource Embraces Linux

Palm OS merchant PalmSource is buying mobile phone ISV China MobileSoft (CMS) in a $22.6 million stock deal to tap into the huge Chinese market and the growing popularity of Linux. Nanjing-based CMS offers a range of mobile phone software and is developing a version of Linux that's optimized for mobile devices.

PalmSource said the thing would run both Palm applications (some apps might require a recompile) and t... (more)

State of Illinois Automates on Adobe LifeCycle

The state of Illinois has linked up with Adobe so state agencies can spend less time with paperwork and interact more with citizens. Adobe’s LiveCycle software is designed to allow some 60 Illinois state agencies and 3,800 counties, municipalities and school systems to automate the completing and processing of forms. The goal is for the state to increase convenience for citizens and reduce costs for itself. The state is in the process of implementing LiveCycle to pre-populate forms with data from back-end systems to improve data accuracy and time. O’Donnell says this is one of the more difficult parts of the conversion. It is estimated that LiveCycle software will save the state of Illinois $12.5 million annually. The larger agencies can eliminate approximately $100,000 a month in paper costs alone. Register for the Real-World Java Seminar in New York Re... (more)
