WebScript Performance Issues

[jpfi]

Hi,
I'm currently evaluating to implement a few WebScript to use Alfresco as a content archive. I've started with a createDoc-Script using javascript with gets an multipart/form-data request sets some attributes and stores the file. An short performance test (Enterprise 2.1, MySql) shows that my script takes overall 200-300ms (filesize 5KB), that is to slow for my requirements.
So, is there any approach to speed up this.
E.g. is a java-backed WebScripts faster than a javascript backed Script?
if true, can java-backed WebScripts handle multipart/form-data request, I didn't find any method regarding this purpose in the WebScriptRequest class?

Thanks for helping,
Jan

Is your timing for the round-trip, server only processing or something else?

Is that after executing the script a few times (to warm up script/template cache)?

Have you switched on web script debug logging to see how long each of the web script components take e.g. javascript execution, template execution etc

You can switch to Java-backed - if you know you're executing in the servlet environment, the WebScriptRequest can be cast to a WebScriptServletRequest, which provides access to HTTPServletRequest.

Hi David,
thanks for your quick answer.
my first timing is the whole http-roundtrip from clientside.
I'm using Apache HttpClient on clientside:

log.debug("\ncall WebScript start");
         // Execute the method.
         int statusCode = client.executeMethod(method);
         if (statusCode != HttpStatus.SC_OK) {
            throw new DMSException("Alfresco call failed! HTTPStatus: "
                  + method.getStatusText() + "::" + DMSRET_USER);
         }
         log.debug("call WebScript end\n");‍‍‍‍‍‍‍‍‍

The script is executed 50 times. That is the alfreso logging output of one script execution:

so, js-script tooks 219ms, template 0s (it is empty…), ~170ms end transaction.
Warning: this timing was taken on a 2GHz/2GB notebook, but I tried the same on a faster machine, there it is a little bit faster.
