Dear all,
I am having the opposite problem than what is reported by most of you and
would appreciate some advice. I am fairly new to GWT and wrote my first app
that runs entirely client side. When a button is clicked it does tens or
even hundreds of thousands flops that are mathematical computations and
outputs the result. I have placed timers in the code and this computation
algorithm takes 2 seconds to run in developer mode (i.e when it runs in
Java). This run time is acceptable. However, when I GWT compiled the app
(into JavaScript) and run it on the web, the same computation function
takes 25 seconds. This latency is unacceptable. My question is what’s the
best way to resolve this? I see 2 potential options and wouls appreciate
some advice on which way I should go and if there are alternative options I
am missing:
*Option 1:*
- - Should I switch the computation functions to run server side?
- How much time does it take the server to send 5,000 doubles
back to the client?
*Option 2:*
- - Should I scratch GWT and the whole JavaScript
conversion/compilation and just have the whole thing run in Java client
side in an applet? I am bummed as I chose GWT as to have the App run on
many different platforms that do not accept the Java Run Time Engine.
- I like the GUI I am using, can GWT and Smart GWT GUIs run a Java
Applet (i.e can I use the same GUI I created with GWT but run the core
components of the app in Java, basically run like it does in developer mode
now but as the finished app?)
Thanks in advance!
Sami
