Dear webware community,
I'm perplexed, I have been playing around with XMLRPC as a way to connect to
a database and deliver content. Please see the code below:(one is a
XMLRPCServlet and the second is a regular servlet)
The is issue is that the XMLRPC servlet is about 8 times slower then the
regular servlet. This doesn't make any sense to me. If I kill the sleep
method, and not close the db connection, then it is really fast, but somehow
that does not feel right. I don't seem to be taking much of a hit by
getting a new connection every time with the regular servlet, so why should
it be so with the xmlrpc servlet? Am I doing something fundamentally wrong
in the xmlrpc?
Any help would be great, and thanks in advance
Jose
