On another machine we tried the same tests and found the code took
1680ms to run 1000 iterations. Interestingly enough we rewrote Sean's
code in Java and retried the tests. From Java we could do 1000
iterations in 1265ms. The Java code is below.
import java.util.*;
import java.io.*;
import org.xml.sax.*;
import com.allaire.wddx.*;
public class STest
{
String xmlContent = null;
WddxDeserializer deserializer = null;
public STest(String filePath) throws Exception
{
deserializer = new
WddxDeserializer("org.apache.xerces.parsers.SAXParser");
readInXML(filePath);
}
public static void main(String args[])
{
try
{
if (args.length < 2)
{
System.out.println("Usage: alchemy.STest filepath
deserializations [iterations]");
return;
}
int iterations = 1;
if (args.length == 3)
iterations = Integer.parseInt(args[2]);
STest test = new STest(args[0]);
for (int i=0; i<iterations; i++)
{
test.run(Integer.parseInt(args[1]));
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
private void readInXML(String filePath) throws Exception
{
FileReader reader = null;
try
{
reader = new FileReader(filePath);
xmlContent = "";
char[] buf = new char[512];
int read = -1;
while ((read = reader.read(buf)) != -1)
{
xmlContent += new String(buf, 0, read);
}
xmlContent = xmlContent.trim();
}
finally
{
if (reader != null)
reader.close();
}
}
public void run(int nTimes) throws Exception
{
Map map = null;
InputSource source = null;
long start = System.currentTimeMillis();
for (int i=0; inTimes; i++)
{
source = new InputSource(new StringReader(xmlContent));
map = (Map)deserializer.deserialize(source);
}
long end = System.currentTimeMillis();
System.out.println("It took: " + (end - start) + " ms to deserialize
" + nTimes + " times.");
}
}
