Why the daemon:

Post #122,047 by admin 10/20/03 2:56:20 PM Reply	Why the daemon: The code needs to be very, very fast, and the trade-off is memory for speed. The daemon can take up to 10 minutes to load all of the data necessary to make the calculations. The datafeed is very high volume and the calculations are non-trivial. One of those few applications that really does need to be extremely efficient. I'm supposing here, but I think the HTTP connection really means "OCX/ActiveX/whateverXitistoday used as a web service in IIS and .NET". I don't have all the details, however; the information was second hand. This is just a suspicion. Many of the same disadvantages apply if it's "C++ through JNI in a Java web service". WRT your question about JNI, that was one of the alternatives I had thought of. If we're wrapping the C++ stuff in a framework, why not use a Java appserver as the framework so it can run on more than just Windows. WRT synchronous responses and JMS, one advantage is that one or both ends can go down and the messages are saved. We get that for free.

I'm supposing here, but I think the HTTP connection really means "OCX/ActiveX/whateverXitistoday used as a web service in IIS and .NET". Get them to spell this out in a design meeting. 2. Suggest that this decision be left for later, when several competing strategies can be tested. Abstract the communication process. 3. When it comes time to finalize the comms, remind them: The code needs to be very, very fast, and the trade-off is memory for speed...One of those few applications that really does need to be extremely efficient. 4. Show the native socket app blowing .NET out of the water. 5. Reintegrate the abstracted comms code for a final speed improvement. Ooh, I can work this Team Thinking, can't I? >:) "There's a set of rules that anything that was in the world when you were born is normal and natural. Anything invented between when you were 15 and 35 is new and revolutionary and exciting, and you'll probably get a career in it. Anything invented after you're 35 is against the natural order of things." Douglas Adams
