Jetty中有多个solr实例，或者运行多个Jetty服务器，密度较低？(Multiple solr instances within Jetty or run Multiple Jetty servers, which is less intensive?)

 我正要开始一个新的linode VPS服务器。我目前在我的开发服务器上同时使用Tomcat和Jetty来为不同的Solr服务，但已经阅读了一下，我意识到Tomcat可能是相当资源的，因此建议我使用Jetty。 我已经有了一个在Jetty1 / webapps / ROOT / 
 
 这是我的问题： 
 
 1）在同一个Jetty服务器中运行2个solr实例是否更好？ 
 
 要么 
 
 2）我应该运行两个不同的Jetty服务器（端口8080,8081都可以使用，因为这些服务器仅用于Web服务） 
 
 以上哪一项将资源密集度较低？ 
 
 说实话，我的偏好是2），运行2个不同的码头服务器，因为要让一个Jetty服务器运行多个solr实例需要相当多的工作，因为我已经有一个运行在Jetty1 / solr中的应用程序/ home，并且必须重新设置它，包括适应多个实例。 对于这个教程也没有很多。 
 
 另外，我还有另一个在Tomcat中设置的Solr实例。 我能否将索引复制粘贴到Jetty2 / solr中，索引是否正常工作，还是需要在Jetty中重新编制索引？ 
 
 干杯

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
