We have a couple of Tomcat installations on customer boxes. Both are running in subsystems, with private pools, and both are running in Java 8 JVMs with starting heap 4096 and max heap 5120.

A WRKSYSSTS at Customer "A," with some 60 users connected to our webapp, is showing

7168.00 2.53 500 .0 .0 3.4 6.2

for the private pool, while at Customer "J," with only around 44 users connected to the same webapp, is showing

7125.00 1.11 200 .3 2.0 66.4 282.1

The non-DB page-faulting seems extraordinarily high.

Anybody got a clue what could be going on here?
