check out this book comparison price:
and enter a book and search. In 12 seconds or so, they can search about 20 bookstores. That's less than a second per bookstore.
when i do this in cold fusion, it would take me probably a minute or more.
Ok, maybe I dont know my cold fusion, but this isn't rocket science.
In CF, the requests are done sequentially down the page, i.e. i will grab amazon's price, then once im done and parsed for the price, i will go to barnes and noble, so on and so forth.
i don't know much about JSP to know if this same bit can be done any differently - namely, how can it done in 12 seconds ? is JSP just inherently faster (which i doubt, since regardless of language I'd think the most time wasted would have been establishing connection with the bookstore servers) or as I suspect some languages may be able to do, it can be programmed to do multithreaded requests, so all 20 requests or so are done simultanously?
