“Why is Spark So Slow?” When Apache Spark works well, it works really well. Sometimes, though, users find themselves asking this frustrating question. Spark is such a popular large-scale data processing framework because it is capable of performing more computations and carrying out more ...

a method that allows an app to access a resource with a given name. This method is pretty popular in theJavaworld, but unfortunately it causes gigantic slowdown in an Android app the first time it is invoked. Of all the apps and SDKs we’ve analyzed (and we’ve analyzeda ton), we’...
Moreover, we do understand the options we’ve got for specific concerns like web, data access, integration in terms of framework, especially for Java. Now, where does Spring shine among all these? Let’s explore. 6.1. Usability One of the key aspects of any framework’s popularity is how...
