Multiple solr instances within Jetty or run Multiple Jetty servers, which is less intensive?

Question

Hi,

I am about to embark upon a new linode VPS server.I currently use both Tomcat and Jetty (on my development server) to serve different Solr, but having read around a bit I realise Tomcat can be quite a resource hog, hence the suggestion for me to use Jetty. I already have a Jetty development server set up with an application in Jetty1/webapps/ROOT/

Here are my questions:

1) Is it better to run 2 solr instances within the same Jetty server

or

2) Should I run two different Jetty servers (port 8080,8081 can both used since these are just for web services)

Which of the above will be less resource intensive?

To be honest, my preference would be 2), to run 2 different jetty servers, because its going to be quite a lot of work to get one Jetty server to run multiple solr instances, since I already have an application running in Jetty1/solr/home and will have to set it up over again, including adapting to multiple instances . There also isnt much in the way of tutorials for this.

Also, I have another Solr instance set up in Tomcat. Can I just copy and paste the index over into Jetty2/solr,will the indexes work as normal, or will i need to re-index them in Jetty?

Cheers

Answer 1

Running 2 different jetty instances will not be resource intensive and will give you the flexibility of bringing down one without the other, we run multiple Jettys behind Apache with no problems

If they are serving different purposes, this would be a good way to go, however, if they are related, then you should look to see if a multi-core setup is an option

There is no need to re-index in jetty, the index files are the same, even moving between linux and windows is not a problem.
