performance exp (was: [SoapRMI] xpp potential cleanup/reset prob lem)

[CHEN,SHIH-CHANG (HP-NewJersey,ex2)]

Hi Alek,

Regarding our discussion before, I would like to give you some 
feedback about my performance experiment. The test basically 
measures 'hits per second' between multiple clients and a Servlet 
running in Tomcat404 with jdk1.4.  Each client sends a simple 
SOAP message to the Servlet and the Servlet only echo it. Both 
clients and server are running on a PIII 933 (with 256 mem) box. 
Concurrent clients are simulated by Radview WebLoad5 .

1. echo without xml parsing: 285 hits per second.

2. echo with SAX paring: 180 ( the sax parser is the one goes
with jdk1.4.)

3. echo with xpp(xpp3_1_08a) parsing: 227 ( create a fresh parser for
each request)

4. echo with xpp(xpp3_1_08a) parsing: 237 ( with parser pooling )

This is a pleasant result that XPP has much less overhead than
sax.

Many thanks for your excellent jobs,
