The Ruby web framework Sinatra needs three lines of code to map a context (web address) with a HTTP GET request handler:
get '/hi' do "Hello World!" end
In Delphi, I managed to implement the same with this code (see the web framework status project status here):
get(TRoute.Create('/hello', function(Request: TRequest; Response: TResponse): TObject begin Result := TStringBuilder.Create('Hello world!'); end));
The Habari message broker client library for Delphi has reached a new record – more than 5,700 message roundtrips per second (on a entry level 6820s laptop). So the Delphi client side sends and receives a total of 10,000+ messages per second, which means less than 100 microseconds per message.

A first demo application for VisualMM is now available for download at http://www.habarisoft.com/download/VisualMMWebDemo.zip (234 KB), it requires Apache ActiveMQ 5 (http://activemq.apache.org).
Start the ActiveMQ broker with this command line:
<path to ActiveMQ>\bin\activemq-admin.bat start xbean:activemq-demo.xml
VisualMMWebDemo.exe uses an embedded Indy HTTP server. The local firewall will issue a warning if you start it. When started, the demo will launch the web browser to show the monitor charts (see http://www.habarisoft.com/visualmm.html for a dynamic example).
The demo writes its own memory allocation statistics to the ActiveMQ broker and reads it back to create the charts.
The next demo will also allow to select from a list of running applications which provide VisualMM data.
