java.lang.Object
org.apache.jmeter.protocol.http.util.DOMPool
- public final class DOMPool
- extends java.lang.Object
The purpose of this class is to cache the DOM Documents in memory and by-pass
parsing. For old systems or laptops, it's not practical to parse the XML
documents every time. Therefore using a memory cache can reduce the CPU
usage.
For now this is a simple version to test the feasibility of caching. If it
works, this class will be replaced with an Apache commons or something
equivalent. If I was familiar with Apache Commons Pool, I would probably use
it, but since I don't know the API, it is quicker for Proof of Concept to
just write a dumb one. If the number documents in the pool exceed several
hundred, it will take a long time for the lookup.

MEMCACHE
private static java.util.HashMap MEMCACHE
- The cache is created with an initial size of 50. Running a webservice
test on an old system will likely run into memory or CPU problems long
before the HashMap is an issue.
