james load testing/performance stuff

[Jeremy Morony <sh...@solamente.org>]

Hello!  I am curious if anyone else could chime in with what kind of 
delivery rates they can achieve with James.  I've posted before on this 
subject, but I've only seen one other thread regarding this issue, and 
it seemed like that person was getting much better rates.

With the set up I have I'm a bit shy of sending 8,000, 70k messages an 
hour. What I really need is much closer to three times that.  Currently 
we use Lyris, which can achieve those rates given our setup.  I'd prefer 
to use James because of its flexibility and it being an open source 
project. (Also I'm less than impressed with Lyris' customer service!)

The test I run is pretty simple.  I have a mailet that essentially works 
like a really dumb listserv -- mail is sent to a specific account, the 
mail is then forwarded to a list of recipients (essentially a big loop 
calling getMailetContext().sendMail(...)).

Here's my set up:
* 1 ghz processor, 1 gig ram, redhat 7.3
* some kind of T1 out... (I don't have the full details at the moment)
* james2.2
   * nntp, fetchpop, and fetch mail commented out of assembly.xml and 
config.xml
   * dbfile spool
   * 20 remote delivery threads
   * 12 spool threads
   * a fairly bare processor pipeline (root only forwards eve
* mysql4.1.something running on a separate host
* jvm running in server mode, heap set using -Xmx=380m

Given all of this, is this typical of James's performance?
                                                      Jeremy.

Eh, that's using 155kbps, which is theoretically full T1 speed.  Buy a 
bigger pipe.
