Folks,
Sadly enough, I have to confirm the performance problem reported by Todd
Wolff <[EMAIL PROTECTED]>. HttpClient's performance as of 2.0 beta-1
degraded almost four-fold compared to 2.0 alpha-3. The problem is fairly
easy to reproduce:
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
public class Test {
public static void main(String args[]) throws Exception {
HttpClient httpclient = new HttpClient();
long s = 0;
for (int i = 0; i < 200; i ++) {
GetMethod httpget = new GetMethod(
"http://localhost:8080/httpclienttest/body";);
long start = System.currentTimeMillis();
httpclient.executeMethod(httpget);
long end = System.currentTimeMillis();
long duration = end - start;
System.out.println("Execution time in ms: " + duration);
s += duration;
}
System.out.println("Average: " + (s / 200));
}
On my system I get average response time of 5ms with 2.0a3 compared to
23ms with 2.0rc1. I have no idea what kind of lunacy we have pulled off
to make that happen. I checked the most obvious suspects:
HttpConnection, wire logs. No solution yet.
