Can Clojure’s thread-based agents handle c10k performance?
I’m writing a c10k-style service and am trying to evaluate Clojure’s performance. Can Clojure agents handle this scale of concurrency with its thread-based agents? Other high performance systems seem to be moving towards async-IO/events/greenlets, albeit at a seemingly higher complexity cost.
how to verify ConcurrentHashMap is threadsafe?
As the jdk doc said, ConcurrentHashMap is thread safe and it doesn’t block multiple thread read. It is not necessary to doubt that since it was under many and restricted test. But I just curious how to tell and write code to verify that.
Requiring multithreading/concurrency for implementation of scripting language
Here’s the deal: I’m looking at designing my own scripting/interpreted language for fun. I’m only in the planning stages right now; I want to make sure I have a very strong hold on exactly how I will implement everything before I start coding.
Help me understand a part of Java Language Specification
I’m reading part 17.2.1 of Java language specification: http://docs.oracle.com/javase/specs/jls/se7/html/jls-17.html#jls-17.2.1
How to keep background requests in sequence
I’m faced with implementing interfaces for some rather archaic systems, for handling online deposits to stored value accounts (think campus card accounts for students).

Why is multithreading often preferred for improving performance?
I have a question, it’s about why programmers seems to love concurrency and multi-threaded programs in general.
Design question about a concurrent forking server
I’m in the early stages of designing a client/server application. The clients will be batch programs that read a file of customer contact data (name, address, email address, phone no’s) and pass these components to the server, which will add them (if not already present) to corresponding mySQL tables and return id’s for each component. In order to boost performance, the server will have spawned four “manager” servers, each tasked with looking up and possibly adding a new row, and will pass the four components via IPC to those managers so that they can work concurrently.
Common Lisp Implementations – threading and multiplatform?
I’m learning Common Lisp, mostly as a “mind gym” hobby thing, but I want to end up with a set of skills that would also be usable “in real life”, because when you learn a language you also accumulate knowledge about module and package management, deployment and stuff, whether you like it or not, so I want to learn with a CL implementation that is also usable in production. So my question is:
