is a stability one. Basically I just dont believe the servlet model can
offer the same sort of stability that the one-hit page model can,
principally because on a php page, if the code raises an exception, it'll
flatten the page, not the server. There can also be issues with locking ,
'leakyness' (not *really* as big a problem with python, but I've seen it
in java servlets despite the touted magic of garbage collection).
Finally I do believe webware is not too hard to kill. I'm sadly having to
reboot the webware install I maintain pretty regularly.
Now all that aside , heres why I persevere: Webware is good! The webkit
offers a pretty straight forward way to generate persistant servlet stylee
without horrible.java.abstact.compsci.evil brain hurt. Its pythonic and
pythonic is nice.
Any process control stuff is going to need a persistant process anyway.
Maintaining serial connections, listening for state data from devices etc
etc. One aproach has been a little more abstraction.
I put together a system for controling a large security camera network
that works *imaculately* that had this;-
control data<---[pc]->control server<-[xml-rpc]---->interface
|
camera data <---[pc's]->storage<------[mjpeg streams]---+
the beauty of that, is that I had a php interface that could talk to the
server while isolating the control server from 'idiot userfinger land'.
I also put together a little delphi app that had dials and knobs and other
eyecandy, and generally it was a functional well apreciated interface and
worked well. The control server runs webware, but not for the web
interface, but rather for xml-rpc. Strange hack granted, but the structure
of webware suited the task perfectly.
Also handy: It needed no db :) I still cant wrap my head around making
mysql threadsafe.

I regularly run apache bench to test my website on my rather slow
800MHz Mac. It serves about 40 pages per second. This is somewhat
faster than PHP runs, and 20 times faster than my old JSP/J2EE
application would run. So I think performance of Webware is top notch.
Also related to performance is reliability and I find Webware very
stable. When one servlet raises an exception, it does not cause
problems for other parts of the website. If the whole thing should go
down, then it will automatically restart.

Hi guys!_________________________________________
I planning to make a system to automatizate the site factory. I use
cheetah and webware, each site will have a standart look and feel, I
will have several sites (the goal is to hit up to 1000 clients in one
year), my worry is with the webware performance. Each site will have
few acess, but grouping all the sites... I think it's about
Is there a reason to worry or webware can handle this? Does anyone
have a big site running under webware?
