Re: [Loadsim-users] Re: LoadSim not finishing simulation

Alright, here is the history...

When I first starting working on this about 1 1/2 ago, I was jusing JDK 1.1.8.
 The implementation of the HTTP client code flat out didn't work (I forget exactly
what the problem was, but it simply didn't work).  So, I hunted around and found
HTTPClient, which using the property that you give, did work.  At the job that
I was doing when I first used LoadSim I only simulated up to around 80 users
(only about 20 per machine).  HTTPClient worked fine.  

More recently, however, I used LoadSim simulating much large numbers of users
(upwards of 200 per machine).  HTTPClient started breaking down and not working
very well.  So, I decided to see if the JDK 1.3 (which is the JDK I use now
exclusively -- we use Weblogic instead of Websphere) had improved their HTTP
client implementation.  To my surprise and happiness it was markedly better.
 So, now, by default, LoadSim uses the built-in HTTP client implementation (which,
for that reason, I would recommend using JDK 1.3 for running simulations). 
LoasSim still ships with HTTPClient, which you should be able to use.

Now, for those interested, the version of HTTPClient that I use is from over
a year ago.  Maybe newer versions work better.  If you'd like to try a new version
check out the link to the HTTPClient site in the acknowledgements section of
the LoadSim homepage (I think LoadSim ships with 0.3.1 and the newer version
is 0.3.2).

Well, that is probably about as cleas as mud, wouldn't you say?
