It depends on the application type. A desktop application is much different than a web application. An application server is much different than a standalone application.
It also depends on the JVM that you are using. JDK5 and later 6 include enhancements that help understand how to tune your application.

PyTables Pro claims that "for situations that don't require fast updates or deletions, OPSI is probably one of the best indexing engines available". However I've not personally used it, but the F/OSS version of PyTables gives already gives you good performance:

This syntax is from Visual Basic, where you can code something like this:

Most likley, you either want to check the $USER environment variable. Other options include getuid and id -u, but searching /proc is certainly not the best method of action. |

Extract the part that accesses the HTTP resources out of your main code. Create an interface for that new component, In your test, mock the interface and return data that you can control reliably.
You can test the HTTP access as an integration test. |

Since the "i" in
get<i>(tup)

The phrase "real-time" covers a fairly large patch of ground.
The vague definition is "software that acts within a bounded response time".
