[httpclient_common]_why httpclient's speed is the same with JDK httpurlconnection
Hi,
I have a problem when trying to comparing the speed between JDK
HttpURLConnection and HttpClient.
Now I have two methods, one is performed with jdk(1.5) httpurlConnection,
the other is performed with httpClient( 3.0.1). Both of them try to download
the same webpage(http://jakarta.apache.org).After<http://jakarta.apache.org%29.After>testing,
the average time which performed JDK httpurlconnection is 200ms,
so as the one which performed httpclient.That means their speeds are almost
the same.
So, since HttpClient use persistence connection default but JDK do not, why
httpClient's speed could not be more fast than JDK?
Another problem is, is it normal to httpclient to use 200ms to download a
page like http://jakarta.apache.org? I mean, when using persistence
connection, maybe this could not be accepted.
Any help will be great appreciated

Hi Craig,
I use JDK5.0. Actually, Some guys told me that HttpClient is very fast. Then
I perform this testing to find how more it runs than JDK httpurlconnection.
And, of course, the test result could not feed my need, in another words, I
think this speed(200ms to download a normal page about tens of kbytes)is too
flow. And, I wonder if my using to httpclient is perfect, I just follow the
apache guide to do that.

What JDK are you using? IIRC, the JDK's HttpUrlConnection class has
defaulted to persistent HTTP connections since at least JDK 1.1 days.
Another problem is, is it normal to httpclient to use 200ms to download a

The timing of something like this, especially on a relatively small page, is
going to be so dominated by the speed of your connection to the Internet
that "acceptable" is in the eyes of the beholder. Is it fast enough for
your requirements? If so, it doesn't matter which technology you choose --
they both work. Is it too slow? Then it doesn't matter which technology
you choose -- they both fail to meet your needs. Is your average need to
download multiple megabytes instead of a couple hundred kbytes? Then the
test you ran is totally meaningless because it did not reflect your real
requirements.

As far as I know, HttpClient does not use URLConnection - it uses Sockets.
This is what gives it the ability to manage connections more flexibly
than URLConnection.

Agree with you. But I think httpclient's target is not only this. Httpclient
has a connection pool to keep the links with the remote http server, and
httpurlconnection download a page with re-opening the connection each time,
why their speeds are not different?

I think the HttpClient essentially use the urlconnection, then i would
ask why httpclient will faster than urlconnection?
I think the benefit of HttpClient is that it manage the connection, that
make your code more neat, you can focus on the business logic...

At a guess, the Oracle code is trying to cast the connection to
OracleConnection or some such. It's not an OracleConnection as DBCP
wraps that with its own Connection implementation.
Try doing:
adTemp = ArrayDescriptor.createDescriptor("ARR_VARCHAR",
((DelegatingConnection)con).getDelegate() );
with an import of:
import org.apache.commons.dbcp.DelegatingConnection;

Sorry for delay in answering.
We already have the configurations done as u said
and that application executes vey well in most of the cases Except wher ever
there is this
piece of code
>>ArrayDescriptor adNumb = ArrayDescriptor.createDescriptor("ARR_NUMB",

Somebody people on the Web mentioned to fetche the inner Delegated
Connection from the wrapped ones
to solve the same, but no refrences were made.
Please We Only have the Exceutable (war file and no source code avaliable

My limitation is limited to JNDI connection changes to be made when running

Please help me

JNDI + dbcp + commons-dbcp-1.2.1.jar
Posted by karthik <ka...@xius.org>.
Hi
Sorry for delay in answering.
We already have the configurations done as u said
and that application executes vey well in most of the cases Except wher ever
there is this
piece of code
>>ArrayDescriptor adNumb = ArrayDescriptor.createDescriptor("ARR_NUMB",
con); << Line number 423
Still we get the ClassCast Exceptions at those mentioned palces....
java.lang.ClassCastException
at
oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:108)
at
com.xius.infinet.ums.UMSBusinessClass.makeNewRolesAdmin(UMSBusinessClass.jav
a:423)
Somebody people on the Web mentioned to fetche the inner Delegated
Connection from the wrapped ones
to solve the same, but no refrences were made.
Please We Only have the Exceutable (war file and no source code avaliable
for the same)
My limitation is limited to JNDI connection changes to be made when running
on Apache Tomcat 5 and above
Please help me
with regards
Karthik

Allen,
If you are familiar with Apache Benchmark [1], you can use similar tool
based on HttpClient [2]. Both tools can optionally enable / disable
connection persistence.
Hope this helps

Thank you Oleg, your tip is useful for me. So do you have good idea to how
to measure the difference between persistence connection and non-persistence
connection? Actually one of my desination in this testing is, how more fast
when use persistence connection than non-.

Essentially you are measuring the speed of JIT compiler, DNS hostname
lookup, and that of the link to your ISP. I suspect this measurement
does reflect the performance of the underlying HTTP engines at all.
Please consider running your tests against an HTTP server on the local
network, making a significant number of repetitions to eliminate data
distortions due to JVM startup, JIT compilation and other factors
You might want to use this benchmarking tool to test performance of
HttpClient [1]. The HttpClient benchmark tool supports a subset of
commands of the Apache Benchmark (ab) and produces similar output.
Hope this helps
