Subject RE: Number of HTTP connections if using keep-alive
Date Fri, 23 Apr 2004 10:44:39 GMT
Hi Sebastian,

Thanks for the response.

I am using JMeter 2.0 with the default HTTP sampler and Tomcat 4.1.

After a little bit of playing with tcpdump I can confirm that, if keep-alive
is being used, *each thread* gets its own connection and will handle 100
requests using that connection before re-establishing it.

I am not sure whether it is Tomcat or JMeter that breaks the connection
after each 100 requests (Tomcat does *not* have maxKeepAliveRequests
specified for the Coyote connector).

Regards,
Ryan.

Depends on the version of JMeter and the Http implementation.

If using 2.0, and the new HttpSampler (which uses Apache HttpClient), then
it should be 1 per thread, though this has not been confirmed. If this is
not the case, please file a Buzilla report, as the intention was to re-use
connections if so requested.

If using the default Http implementation, who knows?
The standard Java interface offers no way to re-use connections. 
If keep-alive is set, it is up to the Java implementation as to what it
does.

Hi,

How many HTTP connections will JMeter 2.0 make if the server is using
keep-alive?  1 per thread / 1 per thread group / 1 per test ?

Thanks,
Ryan
