performance inquiry
Hi.,
I am begining of developing a
standalone/networked/web application. But need to
decide what to use. C2 attracted be 'coz of many cool
features i might use in the future..
But performance issues scares me.... I need advice..
The application need to run standalone or networked
like web app...Considering this..
1. Is it better to do with servlet and jsp: In this
case i have problem with connection pooling and o/r
mapping to database
2. Is it better to use xml stuff with c2: In this i
fear for performance. I fear it might demand high end
configuration user systems compared to no1..
Please advice
thanks

JSP v. XSP (was Re: performance inquiry)
Posted by Anthony Mills <py...@yahoo.com>.
I am not interested in time right now, atleast not ms. Why else would I
want to use XSP? I used XSPs for awhile, but I prefer JSP for a few reason,
and right now one doesn't work. I will consider migrating, as most of my
work is done in classes and XSLT. The first is:
<jsp:useBean id="login" class="com.pyramid6.util.WebLogin" scope="session"
/>
<jsp:setProperty name="login" property="*" />
This makes it real easy and nice to support sessions and read the request
parameters.
The second one, which doesn't work in beta 1 is: <jsp:directive.page
errorPage="error.html" />
This will catch exceptions real easy, and display a nice page for me.
Now the only benifit I saw with XSP over JSP is with databases. I am not
planning on using a database, so this point was lost on me.
JSP is an industry standard right now. While I am sure XSP is gaining
support, I am tring to stick to established standards. I am not real
concerned with this, as my files are only about 20 lines long, and I will
have about five of them.
Thanks,
Anthony Mills

The first access is from the Sitemap compiling. It and the XSP pages can be
precompiled. Cocoon takes roughly 15-20 seconds to start up mainly because of
the number of managed resources it is controlling, and because of the compiled
sitemap. If you make Cocoon load on startup then most of the initialization
will have been done before the first request.
5 seconds is about right for an XSP page.
Keep in mind that XSP is a better match than JSP for Cocoon--there is less
translation and parsing that has to happen. By doing that you will shave off
a few milliseconds per request (10-50ms depending on size of information).

Re: performance inquiry
Posted by Anthony Mills <py...@yahoo.com>.
Hello,
I am developing a web site using JSP and Cocoon 2. I am running two tomcat
web servers (3.2 and 4.0beta) on the same box at the same time. I have a
Pentium III 450 with 192mb ram. I have noticed a few things. First, it
takes a little while to start, about 20 seconds. A page take about 5
seconds to load the first time. After that, I am more limited by my
connection (128kbps up) than I am by my web pages. The pages come back
within seconds. I have JSPs being run through Cocoon 2; I assume that xsp
would have similar speeds. Keep in mind this is not a scientific
measurement, just what I "notice". Also, both web server are running about
34mb, with little interaction so far. One thing to consider when deploying
your app. You can precompiled your jsp/xsp pages. This would speed things
up considerably.
Hope this helps,
Anthony Mills
