tomcat running slow

[samman1238]

I have several contexts running on my Tomcat 4.1.24 server localhost (up to over a dozen now and will need to add more). It seems that after adding one, the server gets slower. Is there a limit to the number of contexts that can be run under one host?

Thanks,
Tracey

I don't know if there is a "limit" as such imposed by tomcat, but the more contexts and hosts you add, then the slower it will get, as tomcat has to add more listners & handler objects. Try editing your catalina.bat or catalina.sh so the command line args to "java.exe" are "Xms512m -Xmx512m" where 512 is the amount of RAM to load tomcat's JVM with.

I'm not sure where to put the following. Can you tell me where in the file to put it??

"Try editing your catalina.bat or catalina.sh so the command line args to "java.exe" are "Xms512m -Xmx512m" where 512 is the amount of RAM to load tomcat's JVM with."

Here is my catalina.sh file:

Depends on what OS you are on.

If on linux, then you use catalina.sh, if on Win32, then you use catalina.bat.

If you are on Win32, then just adjust the lines that I posted earlier to the relevant lines in the .bat file ....

Thanks. I'm on Linux and have made the changes to the catalina.sh file. It seems to be running a little faster.

Under the current configuration, I add new Contexts to Tomcat for each of my customers. I will be adding new customers in the future (how many, I don't know).

Each customer has their own environment entries and data sources that I use to determine which database to use and where to store uploaded files and such.

I know that it will slow Tomcat down the way I'm currently doing it.

What would be a better way to handle this?

Perhaps use Apache httpd server, use virtual host entries, which map to tomcat webapps. In tomcat, only have one <Host> which is localhost, but with each <Context> for each respective customer/webapp.

Or several, or larger servers ...

That's how I have it set up now. In Tomcat, I have one Host (localhost) that I have separate <Context> for each customer. I find that Tomcat is slowing so I want to modify the configuration now before I have more customers and more Context to add to it.

Is this way better than setting up 1 host and 1 <context> and then add more environment entries and data sources to handle each customer?

As you stated in your first reply on my post, the more context I add, the slower it will get. Any other suggestions?

Sorry, not that I know of ... apart from bigger boxes and loads of RAM !!!
