[Bug 57452] New: GZip transferring is slow

https://issues.apache.org/bugzilla/show_bug.cgi?id=57452

            Bug ID: 57452
           Summary: GZip transferring is slow
           Product: Tomcat 8
           Version: 8.0.11
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: tabu-atherah@etq.com

Hello,

In my web application I am using my custom gzip filter for the files .js and
.css.

I have been using my application on tomcat 6 and 7 without issues.

But when I used tomcat 8.0.11, 8.0.12 and 8.0.15 I found slowness in my
application.

After investigation i found That the slowness was caused when receiving GZipped
files (js and css). and when the gzip filter is disabled I do not face any
issue.

I have used the browser to directly request a js file and the content of the
file was returned quickly but the browser keeps loading after that for 20
seconds.
So it seems that the response was sent from tomcat but it was not closed until
after 20 seconds regardless of the file size.

That sounds like a problem with your filter not correctly informing the user
agent of the expected length of the resource. This is a question for the users
list rather than a Tomcat bug.

Thanks you for your response.

But as described above that filter was working correctly with Tomcat 6 and
Tomcat 7.
What was changed in tomcat 8?

Please post to users@tomcat.apache.org to get help: Bugzilla is not a support
forum.

Hint: take some protocol traces of the behavior under Tomcat 6/7 versus 8 and
post those results along with your question on the users' list.
