We are using the APR connector in both cases.

In Tomcat 6, you are using the BIO connector, or possibly the APR
connector. Do you know which you are using?
In Tomcat 8, you are using the NIO connector, or possibly the APR
connector. Do you know which you are using?
When Tomcat starts, it will tell you what kind of connector it is using
like this:
Dec 22, 2015 10:16:52 AM org.apache.coyote.AbstractProtocol init
INFO: Initializing ProtocolHandler ["ajp-bio-8015"]
Dec 22, 2015 10:16:52 AM org.apache.coyote.AbstractProtocol init
INFO: Initializing ProtocolHandler ["http-nio-127.0.0.1-8017"]
Dec 22, 2015 10:16:52 AM org.apache.tomcat.util.net.NioSelectorPool
getSharedSelector
Here you can see I have an AJP BIO-based connector on port 8015 and an
HTTP NIO-based connector on port 8017.
Let's make sure we are comparing apples to apples, here.
