I am running jetty-distribution-8.1.5.v20120716 and jetty-distribution-9.1.2.v20140210 on a windows 7 machine.
And i find that with Jetty 9 the number of classes loaded into memory are a lot more than the number of classes loaded by Jetty 8 especially after the web app has been deployed.
The web application is developed using Spring 3.X and Hibernate 4.1.X, just in case that could have a effect on things
Below are the numbers i have observed, this causes my first request to be responded slowly, and more over i am just curious to know why this happens
In case you are not able to download Jetty 8 you can download it from here
PFA images of my JConsole showing the number of classes loaded in each case
Jetty 8
Without web app -- ~1630
With web app after login -- ~1632
Jetty 9
Without web app -- ~2107 classes
With web app -- ~8700 classes to begin with, and once i access the web application it increases to around ~ 9600 on first request, subsequent requests do not see a spike
