[Opensource] RAM; measuring performance; stress test tool

[larry hamel]

hi Max,

of course, more RAM is better; it depends on how many objects you want cached, etc.  Only testing will tell.

expresso has a means to find out how long each state takes to complete. see the log level of "info" for controller will output durations, i.e.
        <category name="com.jcorporate.expresso.core.controller">
                <priority value="info"/>
        </category>

(along with lots of other trivia.  you can change this logging level on the fly; just edit the file--it should be reread)

this measurement is independent of any internet lag, so it should reflect your RAM cache and host tuning.

consider using the Morebot tester to stress your site.  see link in footer.  you can run it remotely, or (if you can run a java process on your host site), you can run it locally on the host itself, calling localhost   

hmm, do they run through apache <--> servlet engine?  (i.e., servlet is on 8080 or thereabouts, but clients go through apache to this engine)

so far so good with eApps for you?

ps. forum is faster
