Don’t Like Throttling?


Guess what – you are stuck with it. So you can chose to let the underlying system handle it or you can chose to dictate how your traffic should flow.

Do not let the illusion of control dictate the performance. Be the one who needs to control and manage the traffic

High availability design


Of course, eventually with many fixes over time you will eradicate a lot of cases that led to failures but it would have taken you so long and the reputation that the brand holds do dear is already damaged. You can chose to design for High Availability or you can chose to be just like Indian Railways – always delayed and always cancelled – a perspective that will i don’t think will ever be fixed no matter what they do.

Caching Architecture (Adobe AEM) – Part 1


If you ever have designed or want to design a platform/site that needs to support some steep non-functional requirements like 1Billion hits, then you have to rever to using cache as a key part of the framework. How cache as we have known it back in the days is not longer just plugging in a library and start writing to it. There is a lot more to it when we talk in context of a Digital Media platform and how you deal with very high loads. This article will talk about principles that will help you design for
– Performance: Caching is a pattern that we employ to increase the overall performance the application by storing the (processed) data in a store that is a) closest to the consumer of the data and b) is accessible quickly
– Scalability: In cases when we need to make the same data-set available to various consumers of the system, caching as a pattern makes it possible for us to scale the systems much better. Caching as we discussed earlier allows us to have processed data which takes away the need to run the same processing time and again which facilitates scalability
– Availability: Building on similar principles as of scalability, caching allows us to put in place data in areas where systems/components can survive outages be it network or other components. While it may lead to surfacing stale data at points, the systems are still available to the end users.

Write Through Cache


I was a young budding developers when I was first introduced to the concept of Cache. My Senior Architect then told me Cache is a component that will magically store data so that future requests of that same data will not be to the Remote Server, and hence it will improve the performance of our […]

Concurrency Pattern: Producer and Consumer


In enterprise world, where performance holds the key to everything; the Concurrency patterns bring to table a very interesting and effective solution. One specific pattern Producer and Consumer allow us to write programs with high throughput and get the job done much quickly. This pattern provides us a solution for a common problem where we have to migrate data form System 1 to System 2 and in the process we need to do three tasks: Load data from Database based on groups, Process and Update the records back

Java Collections | Performance Benchmark


Managing list or collection of objects is a very common scenario. In addition, managing that list effectively, that provides the optimum performance is also a very common need. The Java programming language offers many in-built data types for representing and modeling collection of objects. Some of the commonly used data types are: java.lang.ArrayList java.lang.HashSet java.lang.TreeMap […]

Performance | Advanced DataGrid rendering


In one of my projects there were some custom needs where we wanted to display values in cell based on the data passed. This led us to write custom ItemRenderer’s. Considering that we were creating multiple instances of Containers like Canvas, Box with-in led me to thinking how would Advanced Data Grid, respond to this […]

Performance | Reducing SWF file size


If you are developing an Enterprise application in Flex, you must be asking yourself “how do i reduce the size of my SWF file?”. This is important because, bigger the file, the more time it will take to load. There are a few ways to do, but one of the ways that is not so […]

Performance Benchmarks – C++


If you are a C++ developer, this benchmark release will interest you very much.

YSlow?!


Nice name 🙂 I came across this Firefox add-on a few days back. My first reaction was “this is kewl”, but as I started to use the same with my Firefox and looked at the various stats for applications all of this started to look “Hot”. For a simple application that I was working on, […]
