Tomcat + Struts in Production Environment
Hi All! Just a little intro about my work and myself.
I'm the only employee of a startup software company
writing database solutions. I'm told to write an
application for POS, invoicing and inventory modules
that should scale for around less than 30k but greater
than 10k transactions per day. I'm using MYSQL and
JavaBeans+JDBC solution for database retrievals. For
my backend modules (invoicing and inventory), I wrote
them using struts framework and displays the
information in HTML. For my frontend module (POS), I'm
thinking of writing a "rich client" application and
possibly deployed using Java Web Start. I'm almost
through with the backend modules except for minor bugs
and tweaks. Now my question is this, without EJBs,
will my servlet/jsp/struts solution scale for 10k-30k
transactions per day? Do you think the overall
penalty/overhead for my JDBC connection will degrade
the entire performance? Is there any way for me to use
connection pooling without EJB? Or should I migrate my
javabeans to EJB?
Thanks in advance.
Regards,
L. Yeung

Regarding Struts's scalability, I don't think that it will be the bottleneck
in your application by far. We have successfully used Struts on a site that
handles 1,000+ transactions per minute, so even 100,000 a day is no sweat
for Struts itself.
I think it's your DB that will be the bottleneck, so make sure you are using
a connection pool, etc. Connection pooling is not an EJB thing only, it's
something provided by your server.
One other thing... heavy use of JSP tag libraries can noticeably degrade
performance. One forgets how much code they generate. We generally use only
the "html" and "template" tags since they are most useful. You can get away
without "bean" and "logic" in many cases.

Isn't PostreSQL much slower than MYSQL? But I think it
has nice features which MYSQL doesn't have.

I think the advantage of using EJB is that the App
Server has connection pooling. And AppServers supports
caches (??)

Yeah it connects a lot, for catalog retrievals and
could possible have many inserts (especially in POS
module). I need to write an non-EJB components for the
mean time. But I need to make it portable to EJB if
the transaction baloons up thrice as much.

Also consider Mylex SCSI caching controller or similar (check tpc.org
for ratings). The bottle-neck is almost always the DB so place your
concern there. You can always do a stress test to generate X number of
transactions per hour with the first page you develop. I use the
Microsoft Stress test tool, it is free. (MS is good at generating stress).

Which do you think is faster under load: JavaBeans or EJBs? Why do you
think that?

It depends. Do they connect and do a lot of work? Or connect, do one
thing and go away. Any J2EE app. server has connection pooling, it is
required to be a J2EE standard. Or you can use CodeStudio.com for
pooling. It is free.
