I am working on a legacy application and the application to the natural is already a little slow, I believe that by the way it was developed, but after updating the version of java 7 to java 8 and Tomcat 7 to Tomcat 8 the application takes almost 2 minutes to load the home screen, before it would take at most 10 seconds.
- vraptor 3.4.1
- Tomcat 8.0.47
- jdk 8
I believe that the slowness is occurring by the extremely slow delivery of content to the browser, because all requests are taking too long to complete, some examples:
- bootstrap.min.css 19.6k: 10.07 seconds to download
- font-awsome.min.css 5.7k: 20.27 seconds to download
These times were taken from the browser with the application running localhost.
I could provide several examples, but they all follow a defined pattern: the first 6 files (maximum number of parallel browser requests) take all at least 10 seconds, the next 6 take at least 20 seconds and so on.
I know I’m providing very little information but I really don’t know why I’m slow or where to start.
Could someone please help me?
