I have a page on web mathematica that reads the value of the POST request's payload and responds accordingly. I've noticed a huge difference in the time the server takes to respond depending on the content type of the request, and I can't really figure out why.
multipart/form-data-> about 50 msx-www-form-urlencoded-> about 1100 ms
The content of the page is irrelevant, I've removed everything, leaving only "Hello World" and it still behave like that. The length and the content of the request's payload are irrelevant too. I've reproduced this on both windows and unix.
For other reasons I would prefere to use `x-www-form-urlencoded, but that wasted second is unacceptable... Any clues?
webMathematica 3.4.2 tomcat 7
EDIT:
I was wrong about the size of the payload being irrelevant. I've found that the request is fast if the Content-Length is less or equal 1024 bytes, slow from 1025 onward.
EDIT2: Implementation details
Here is the toy jsp:
<%@ taglib uri="http://www.wolfram.com/msp" prefix="msp" %>
<%@ page contentType="text/plain; charset=UTF-8" %>
<%@ page trimDirectiveWhitespaces="true" %>
<msp:evaluate>
ExportString["Hello world", "RAWJSON", "Compact"->True]
</msp:evaluate>
And here the calls to it:
