Now though my question is about the above WebAppDeploy. If just '/' is

actually invoke the servlets. If I attempt something like :
WebAppDeploy /www/foo/java/servlet conn /servlet
where /www/foo is document-root and having to create a WEB-INF symlink
to that directory from inside of it, in order to actually have the
servlet fire the request is {host}/servlet/servlet/HelloWorld, which
looks like kind of silly. So, just a conn / would probably work, but I
don't need all the overhead of dealing with a module if it's not
necessary for each request. And does the mod_webapp work with JSP's or
is it back to the mod_jk world for that stuff?

IllegalStateException from jsp:include..
It looks like on a jsp:include from Tomcat 4.0.1 on Solaris x86 (JDK
1.3.1_01) I'm getting a IllegalStateException when the JSP engine
actually attempts to include the file (Stack Trace from include in JSP
is at the end). For the Apache side of things I've got document-root set
to /www/si/sifk/ and a symlink from
${CATALINA_HOME}/webapps/ROOT/WEB-INF/classes to the actual location of
all the Servlets in the document-root (NFS mounted to be spread across
multiple machines and one deployment sport). Is there a way to get the
JSP/Jasper engine to realize a different ROOT than the one the servlets
are loaded from? I'd like to set the JSP root to the same as the Apache
document-root so that all things are be dployed at once and I don't have
to go and adjust symlinks for new things. I'm guess that it's either
Jasper/Catalina/Tomcat or the JVM that's having an issue with attempting
to include a file from a symlink.

Re: Tomcat Performance..
Jeff Kilbride wrote: I'm a little surprised by your performance numbers, actually. I wrote a small servlet to test Apache + Tomcat + MySQL speed and tested it on an intel celeron 433MHz box with a single IDE drive and 128MB of RAM -- pretty much a piece of crap. I ran Tomcat 3.2.1, ajp13, Apache 1.3.19, the IBMJava2-13 JVM, RedHat 6.2 with the 2.4.3 kernel -- with almost no configuration tweaking (default server.xml, default JVM settings). The servlet would take a GET request, insert the parameters into the database, and then redirect to another page on the same box. I was able to get 54 inserts per second into the database with 25 threads running, which equates to 108 requests with the redirect. I was running a connection pool of 20 connections to the database. The network was a 100bT LAN and I ran each test for 10 minutes -- multiple times with the same results. I tested mod_jk/ajp13 against mod_jserv/ajp12 and found mod_jk to be almost 60% faster -- plus it's performance was a lot smoother. I was using the Web Performance Trainer software from http://webperformanceinc.com/products/ Did you synchronize either your doGet() or the method that did the insert/update into the DB? Maybe the problem does lie in Tomcat 3.3 and I should back out to 3.2.2. The problem dosen't seem to be Hardware or OS related since it's the same crappy performance on both an Ultra 60 and a Intel box. I started off the testing with the request that I know should be the slowest out of all of them since it is a synchronized method for a Database insert/update. I'll drop the U60 back to Tomcat 3.2.2 and see if that gets any better numbers out of it. -- Steve Brunton [EMAIL PROTECTED] Phone: 404-827-2756 Chief Engineer Enterprise SystemsOne CNN Center, Atlanta GA CNN Internet Technologies ICBM: 84W 23' 45 33N 45' 29 * Money Isn't Everything, But it Sure Keeps the Kids In Touch *
Re: Tomcat Performance..
Jeff Kilbride wrote: No, I didn't synchronize either. That would defeat the purpose of my connection pool and *really* slow down performance. Right, that's why I expected crappy performance from the servlet as a whole, since I synchronized the method. What has me bothered is the 39 requests per second on iPlanet, 16 requests per second talking straight to Tomcat 3.3 and 4 requests per second talking to Apache 1.3.19 w/ mod_jk.so in ajp13 mode talking to Tomcat 3.3. I could understand like a 30%-50% performance drop from iPlanet-Apache, but from 39 RPS to 4 RPS seems a bit absurd. If you're synchronizing access to the method that does your insert/update, then that's your bottleneck. Do you really have to synchronize it? Can you rewrite the SQL to avoid the overhead of synchronizing in Java? Are you synchronizing the entire method or just the block of code that does the insert/update? Well, let's just cut the whole insert out of the formula and state that it's an update. It has to be synchronized since a request from a luser comes in, we take that data get data out of the database, add them together and update it back into the database. It's not a scientific kind of thing nor are lives depending on it, but if it's not synchonized and I push 1000 requests against it about 100 of them actually get counted, while syncronized they all get counted. And actually in testing against iPlanet itself the syncronized was just a smidge faster than non-syncronized. We think it has something to do with Oracle's row locking on updates. -- Steve Brunton [EMAIL PROTECTED] Phone: 404-827-2756 Chief Engineer Enterprise SystemsOne CNN Center, Atlanta GA CNN Internet Technologies ICBM: 84W 23' 45 33N 45' 29 * Black holes are where God divided by zero. *
Re: Tomcat Performance..
Craig O'Brien wrote: Hello, Those are similar numbers to what I have been getting on Intel platforms with Tomcat3.2.1. You can boost Tomcat to about 90 pages per second using ajp13, mod_jk, and reducing the log level to warn rather then info. (of course your Servlet code makes a difference) There is actually a bug in the logging with Tomcat 3.2.1 -- info actually gives you debug log level. According to GOMEZ the ajp13 connector is not fully optimized and mod_jk is still unfinished. Apache's performance can be boosted by limiting the modules that you use and reducing log levels as well. Interestingly, I was testing a servlet which displayed date, session variables, and generated a random password and clocked in at about 88 pages per second with mod_jk. When I direct connected to Tomcat I was able to get 463 pages per second with no errors so there is allot of potential there. I was able to top out at 1107 pages per second on that servlet with Resin. Consider your bandwidth, of course, 50-60 pages per second can easily overwhelm a T1 line. Indeed with a standard 45k+ page you would be lucky to anywhere near 25. Ok, since some questioned my methodology before I've re-run the tests on the same box (a Sun Ultra 60 2x360 Mhz with Solaris 6 installed). The same servlet has been used for all this testing. Bandwidth isn't a problem in our case since I'm pretty sure the two OC-48's and seven OC-3's can handle pretty much whatever we've got coming in. All tests were run with 1000 requests and a concurrency of 10. Apache 1.3.19/Tomcat 3.3M2 with mod_jk in ajp13 usage mode turned out around 5.37 requests per second with a very very very high IO wait. One question would be does the mod_jk module open adn close a connection to the Tomcat engine for every request? That would surely hurt performance. Talking straight to Tomcat we get 16.11 requests per second. No IO Wait and it just does it's thing. iPlanet 4.1SP6 will whip out about 38 requests per second. The apache build is just a straight build with only the mod_so module installed along with the default settings. mod_jk was setup with 'warn' as the logging option even though a 'none' would be nifty. So it sort of goes back to the original question of is 3.3M2 the way to go or the 3.2.x family or possibly the 4.x for the best performance? What about the Apache 2.x tree? -- Steve Brunton [EMAIL PROTECTED] Phone: 404-827-2756 Chief Engineer Enterprise SystemsOne CNN Center, Atlanta GA CNN Internet Technologies ICBM: 84W 23' 45 33N 45' 29 * If at first you don't succeed...blame someone else and seek counseling *
